What is a panic bar, and does your Lancaster business door need one?
A panic bar is the horizontal bar mounted across the inside of an exit door. Push it and the door unlatches. People in the trade call it a push bar, a crash bar, an exit device or panic hardware. The names change, but the job is the same: anyone can leave a building quickly, in the dark or in a crowd, without a key, without twisting a knob and without knowing how the door works.
Whether a particular door needs one depends on how the building is used, how many people it holds, and whether that door sits on a required exit path. Those calls belong to your building department and fire officials, not to a locksmith. What we can do is tell you what we commonly see, read your correction notice or plan note with you, and install hardware that matches what the inspector is asking for. If you have a written notice, have it ready when you call.
The doors we usually see involved are rear exits on retail units, side doors on warehouses and shops, doors in offices and meeting halls, and kitchen or storage exits in restaurants. In each case the same question comes up: when someone pushes on this door in a hurry, does it open every time? If the honest answer is not always, it needs attention. This page covers that work. If you are locked out of a business rather than needing exit hardware, that is a different call, and our business lockout service covers it.
Panic bar repair and replacement: when to fix it and when to swap it
Exit devices are mechanical parts that get pushed thousands of times. They wear in predictable ways, and most problems announce themselves before the door fails completely. A device that is merely annoying today can become a safety and inspection problem tomorrow, because an exit door that sticks is the exact thing the hardware exists to prevent.
- The bar sticks down or springs back slowly after you push it.
- The latch does not fully retract, so you have to shoulder the door.
- The door swings shut but does not latch, or latches only if you pull it hard.
- The bar rattles, sags or has come loose from the door because of worn screws or a cracked mounting.
- The outside trim, lever or key cylinder no longer works, which locks out staff who need to enter from outside.
- The dogging feature (the setting that holds the latch retracted during business hours) is stuck or will not release.
- The strike on the frame is bent, misaligned or worn, so the latch catches on the way in.
- The device is alarmed and sounds when nobody has used the door, or does not sound when it should.

Call (213) 577-1366Repair or replace: how we decide
Many exit device problems are repairable. A worn strike, a loose mounting, a dirty or dry latch mechanism, an out-of-adjustment rod and a failed trim cylinder are all common repairs, and when the device is otherwise sound, repair is usually the more economical route. Push bar repair and exit device repair often come down to cleaning, adjusting and replacing a small number of parts.
Replacement makes more sense in other situations. The model may be discontinued so parts are hard to find. The housing may be cracked or bent from a forced door. The device may be the wrong type for the door, which is common when a previous installer used whatever was on the truck. Or the same door may keep failing after repeated repairs. We tell you which category your door falls in, and we show you the worn part so the recommendation is not a guess. If the repair is cheap and sensible, we say so.
How we handle a panic bar installation, step by step
Exit hardware is not a one-size job. The door material, door width, frame type and the way the building uses the door all change what goes on it. This is the order we work in.
- You call (213) 577-1366 and describe the door: single or double, wood, hollow metal or aluminum storefront, glass or solid, what hardware is on it now, and whether staff need to get in from outside. Mention any fire-rating label on the edge of the door or any inspector note.
- We look at the door and frame in person. We check door thickness, the width of the stile on aluminum doors (a narrow stile limits which devices will fit), the swing direction, the condition of the frame, any existing hardware preparation, and whether the opening carries a fire label.
- We choose the device and the outside trim, and explain the choice to you before we start. If something about the door will not work with the device you had in mind, we say so at this point rather than after drilling.
- We install: template the door, make the cuts, mount the device, set the strike, adjust the latch and any rods, and fit the outside trim. If the old device leaves extra holes, we deal with them rather than leaving the door looking half-finished.
- We test it properly. That means cycling the bar many times, closing the door from several distances, checking that it latches on its own, and confirming it releases with a light push. If the door has a closer, we make sure the closer actually brings it home, since an exit device only works as designed if the door closes and latches.
- We walk you through it: how the dogging works if there is one, how staff enter from outside, what to listen and feel for as it ages, and what the building owner should keep for inspection records.

Call (213) 577-1366Rim, mortise or vertical rod: which push bar fits your door?
Choosing the wrong style is one of the most common reasons an exit device does not work well. Here is the plain version of the main types we install as part of panic hardware installation and replacement.
- Rim devices mount on the surface of the door and latch onto a strike on the frame. They suit most single doors and are the usual choice for a straightforward replacement.
- Mortise devices use a lock body set into the edge of the door. They are common where the door already has a mortise pocket and where a key-operated outside lever or cylinder is wanted.
- Surface vertical rod devices latch at the top and bottom of the door through rods on the face, and are common on pairs of doors without a center post.
- Concealed vertical rod devices hide the rods inside the door, which gives a cleaner look but requires a door built for them.
- Fire-listed exit hardware is made for fire-rated openings. A fire-rated door needs hardware appropriate for that rating, and features like dogging can be restricted, so we check the label before adding anything.
What affects the cost of panic bar installation in Lancaster?
We do not quote prices on a web page, because the same phrase, panic bar installation, can mean very different amounts of work. What moves the cost is straightforward, and we explain it on the phone so you can compare quotes fairly.
The first factor is the device itself: the style, the finish, the brand and the rating. A basic rim device on a plain steel door sits at one end, while a fire-listed concealed rod device on a pair of doors sits at the other. The second is the door and frame. Aluminum storefront doors with narrow stiles, doors that need new preparation, damaged frames, and doors with old hardware that has to be removed and patched all add labor.
Third is what else the door needs. An exit device on a door with a worn closer or a bent hinge will not perform properly, and fixing the door is part of the job. Our door closer repair work is often done alongside exit hardware for this reason. Fourth is trim and function: outside lever trim, key cylinder, alarm, or electric latch retraction for access control each add parts and work. Finally, repair versus replacement matters, as explained above. When you call, we ask the questions that settle most of this, and we explain the quote line by line.

Call (213) 577-1366Exit door hardware in Lancaster: desert heat, wind and dust
Lancaster sits in the Antelope Valley high desert at about 2,350 feet. Summers bring triple-digit heat, winter nights can drop below freezing, and strong winds carry fine blowing dust. That combination is hard on exit doors in particular. Metal doors and frames expand and contract through those swings, which is why doors and frames stick seasonally, and a push bar that closes crisply in April can drag in August. Dust gets into latches, strikes and rod mechanisms on doors that face outdoors, and a door that is rarely used, like a back exit, is the one that gets gummed up unnoticed.
That matters for how we install. We set clearances with seasonal movement in mind, we adjust latches so they have margin rather than a perfect-day fit, and we point out where wind-driven dust is likely to collect. Outdoor-facing exits benefit from periodic cleaning and a light application of the right lubricant, not heavy grease that holds dust.
Where we work in town varies. Storefronts and shops along The BLVD in Downtown Lancaster often have older doors and closers, and a failing exit door there is frequently a combination of the push bar and a tired closer, so it pairs naturally with storefront lock repair. Industrial buildings along Sierra Highway and Division Street have side and rear exits where key control and exit hardware go together: who can enter from outside, and who holds the keys. The westside, ZIP 93536, has newer commercial and community buildings from the larger stucco-tract growth, while East Lancaster and ZIP 93534 and 93535 include older central-city buildings where the original exit hardware may be decades old. We do not assume what is on your door. We look at it.
Lancaster is about 67 miles from our storefront at 10740 Wilshire Blvd in Westwood. We plan for that by asking enough questions on the phone to bring the right device, trim and strike with us rather than driving out with a guess. If we need to order a particular part, we tell you plainly.
Why call Wilshire Lock & Key for exit device work
We have been in business since 1987. David, the owner and lead technician, oversees the work, so the people who answer questions about your door are the same ones standing behind how it is installed. We have a storefront in Westwood and mobile service vans, and we serve 140 cities across Los Angeles and Ventura counties, Lancaster included. When you call, you reach us directly rather than a dispatch middleman who passes your job to whoever is free.
The phone is answered 24 hours a day, seven days a week, year-round, at (213) 577-1366. That matters with exit hardware, because the problem often shows up on a Friday evening when a door will not release or a door will not latch and a business cannot close safely. If a door is a security problem right now, our 24-hour locksmith service is the same company and the same phone number.
Exit devices also sit inside a larger picture of how a building is secured. If you are planning keys, restricted keyways or electric entry, we can also help with commercial door hardware as a whole, and with access control installation when exit devices need to work alongside card readers or electric strikes. For building-wide key schemes, a master key system keeps the outside trim keys organized. We keep this page about exit devices, and we will point you to the right service when the job is bigger than one door.

Call (213) 577-1366What to ask any locksmith about licensing and code
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, called a BSIS LCO license. Ask any locksmith for their license number before they start work, and check it with the state if you want to. That includes us. It is a reasonable question and a good company will answer it without fuss.
On the code side, a few other questions are worth asking. Does the installer ask about the door's fire rating? Do they ask whether the door is part of a required exit path? Will they test the door under normal closing conditions, not just once by hand? Will they tell you honestly if the door or frame needs work before a device can function? An installer who skips these questions is installing hardware, not solving the egress problem.
We work to what your plans, inspector and the manufacturer's instructions call for. We do not approve or sign off on your building. That is the job of your local building and fire officials, and when you have a correction notice we are glad to work from it.
How to prepare before we arrive
A little information saves a lot of time. This is what helps us most.
- A photo of the inside and outside of the door, the existing hardware and the edge of the door where any fire label would be.
- The make and model of the existing device if it is printed on the housing or the end cap.
- Whether the door has a closer, and whether it closes the door all the way on its own.
- Whether staff need to unlock it from outside, and with a key, a lever or a card.
- Any inspector's note, correction notice or plan sheet that mentions the door.
- Who will be on site to let us in and who can approve the work.
Frequently asked questions
What is the difference between a panic bar, a push bar and a crash bar?
In everyday use they are the same thing. Panic bar, push bar and crash bar all describe a horizontal bar that releases a door latch when pushed. Exit device and panic hardware are the more formal trade terms. The differences that matter are the style (rim, mortise, vertical rod) and whether the device is fire-listed.
Do I need a panic bar on my Lancaster business door?
It depends on the building's use, its occupancy and whether that door is on a required exit path. Your local building and fire officials decide that, not us. If you have a correction notice or a plan note, call us at (213) 577-1366 and we will install hardware that matches it.
Can you repair my existing exit device instead of replacing it?
Often, yes. Worn strikes, loose mountings, sticking latches, out-of-adjustment rods and failed trim cylinders are commonly repairable, and repair is usually the more economical route. We recommend replacement when parts are no longer available, the housing is damaged, or the device is the wrong type for the door. We show you the worn part either way.
Can a panic bar be installed on any door?
Not any door, but most commercial doors can take one. The door material, thickness, stile width on aluminum storefront doors, the frame condition and any fire rating all affect what fits. Some doors need preparation or a different style of device. We check these before we choose hardware.
Can people still enter from outside if the door has a panic bar?
Yes, if the device has outside trim. Trim can be a key cylinder, a lever or a fixed pull, depending on how you want the door used. Exit-only doors have a blank plate on the outside. We discuss which option fits the way your staff and customers use the door.
My exit door sticks in summer and in winter. Is that the panic bar?
It might be, but in Lancaster the door and frame are just as likely to be the cause. High-desert heat and cold swings make doors and frames move seasonally, and dust collects in latches and strikes. We check the closer, hinges, frame and strike alongside the device, and adjust or repair whichever part is actually at fault.
Can exit devices work with card readers or electric locks?
Many can. Some devices are made with electric latch retraction or electric trim for use with access control. The exit side still has to release freely. If you are planning that kind of setup, we look at the whole opening, and our commercial locksmith team can help plan how the door will function.
How do I know a locksmith is properly licensed?
California requires locksmith companies to hold a BSIS LCO license. Ask for the license number before work begins and verify it with the state. Beyond licensing, ask how they handle fire-rated doors and testing. A good installer answers those questions plainly.
