What is a panic bar, and why does the one on your door matter?
A panic bar, also called a push bar or crash bar, is the horizontal bar across the inside of an exit door. Push on it from anywhere along its length and the latch pulls back, so the door opens. Nobody needs a key, a knob, or any knowledge of how the lock works. That is the whole point. In a crowded or smoky room, people push, and the door has to give.
Because of that, the hardware is regulated differently from an ordinary lock. Whether a door needs panic hardware depends on how the building is used and how many people it holds, and your local building department or fire marshal makes that call, not us. What we can do is install the hardware correctly, repair what is failing, and tell you plainly when a door is not set up the way an exit door should be.
This page covers panic bar installation, panic bar repair and panic bar replacement for San Dimas businesses and property managers. If you are not sure whether your exit door is working the way it should, that is a good reason to call before an inspector or an emergency finds out for you.
What goes wrong with panic bars and emergency exit doors?
Exit devices live a hard life. They are pushed thousands of times, slammed by carts and deliveries, and left propped open by staff who want a breeze. Most of the emergency exit door repair calls we see come down to a short list of problems.
- The bar sticks down or does not spring back, so the door will not latch and sits slightly ajar.
- The latch is worn or misaligned with the strike, so you have to lift or shoulder the door to get it to catch.
- The outside trim, the lever or pull that lets staff in with a key, is loose, spinning, or no longer retracts the latch.
- The door closer is weak or broken, so even a good exit device never gets the chance to latch.
- Someone chained, wedged or screwed the door shut from the inside. We will not restore a setup that traps people, and we will say so.
- The device is the wrong type for the door, often a leftover from a previous tenant, and was never properly fitted.
- Cheap or mismatched replacement parts were used in an earlier repair, so the bar looks fine but does not work smoothly.
How do we install or repair a panic bar, step by step?
Every exit door is a little different, so we start by looking at it rather than quoting from a catalog. Here is how a typical job goes.
- You call (213) 577-1366. We ask what the door is, what it is doing, and whether the building is open to the public, so we can bring the right parts.
- We inspect the door itself: its material, width, thickness, swing direction, and whether it is a single door or a pair. A rating label on the door or frame tells us if it is fire-rated, which limits what hardware can go on it.
- We check the surrounding pieces: closer, hinges, frame, strike and threshold. An exit device cannot make up for a door that drags or a frame that has shifted.
- We explain what we found and what the options are, including the lighter-cost route where it is safe and sensible, and where a full replacement is the honest answer.
- We install or repair the device: mounting the bar, fitting the latch or rods, setting the strike, and fitting any outside trim or cylinder you need.
- We test it repeatedly. The bar should depress with light force, the latch should retract fully, and the door should close and catch on its own every time.
- We walk you through how it works, including any key-control or dogging features, and point out anything else on the door that needs attention.

Call (213) 577-1366Which exit device fits your door?
Choosing panic hardware is mostly about matching the device to the door, not picking a favorite brand. Here are the main types we work with and where each tends to fit.
Fire-rated doors need hardware listed for fire doors, and doors in some occupancies need specific features. We read the labels and confirm what the door requires rather than guess, and where the code question belongs to the fire marshal or building department, we will tell you to ask them.
- Rim devices: the latch mounts on the surface of the door and catches a strike on the frame. These are common on single steel or aluminum doors and are often the simplest to install or replace.
- Surface vertical rod devices: rods run up and down from the bar to latch at the top and bottom of the door. They suit the inactive leaf of a pair of doors or doors with no center post.
- Concealed vertical rod devices: the rods are hidden inside the door for a cleaner look, and they usually mean more labor.
- Mortise lock devices: the latch sits inside a pocket cut in the door edge. They are sturdy and common where a heavier commercial setup is needed.
- Alarmed and delayed-egress devices: these add a horn or a short release delay. They carry extra rules about where they are allowed, so we confirm the approval path first.
How much does panic bar installation cost in San Dimas?
We do not quote prices on a web page, because the same phrase, panic bar installation, can describe very different jobs. What we can do is tell you what moves the cost, so you can see why a phone call and a quick look at the door matter.
The first factor is whether you need a repair or a replacement. Adjusting a latch, replacing a worn part, or realigning a strike is usually the more economical route when the device is basically sound. If the body is bent, the finish is failing, or parts are no longer made, replacement is the better use of your money.
The second is the type of device. A basic rim device on a single door is a simpler job than a vertical rod setup on a pair of doors, and a mortise or alarmed unit adds labor and materials. Fire-rated applications need listed hardware, which narrows the choices.
The third is the door itself. Hollow metal, aluminum storefront, and wood doors each take hardware differently. Cutting, reinforcing, or drilling for a new device takes more time than swapping like for like. A door that is out of square or a closer that needs replacing adds to the scope.
The fourth is trim and keying: whether you want a key-operated outside lever, whether it should match your existing key system, and whether the device needs to tie into access control. Finally, timing and travel play a part, since an after-hours emergency call is different from a scheduled visit. San Dimas is a good distance from our Westwood base, so we plan the trip properly. Once we see the door, we give you the answer in person or by phone before work begins.

Call (213) 577-1366Panic bar work around San Dimas: downtown, the corridors and Via Verde
San Dimas has a mix of building types, and each brings its own exit-hardware situation. We serve the whole city, ZIP 91773, and here is how it tends to play out.
Downtown San Dimas, the Bonita Avenue district, has a western-themed streetscape with older storefronts, and many of those buildings carry legacy commercial hardware. A back door that opens onto an alley may still have an old push bar, a surface latch from a previous tenant, or a door that was never fitted for exit hardware at all. Storefront hardware service downtown often turns up an exit door that needs a new device or at least a thorough rebuild. If the front glass door is giving you trouble too, our storefront lock repair service covers it separately.
Along the Foothill Boulevard (Route 66) corridor, the Lone Hill Avenue corridor and the Arrow Highway corridor, you will find the kind of commercial properties where exit doors take a beating: rear service doors, stockroom exits and side doors that staff use all day. A device that sticks in one of those doors tends to get propped open or ignored, and that defeats the purpose of having it. A prompt repair keeps the door doing its job.
Via Verde is mostly residential, with townhomes, condos and golf-course homes, but a planned community has shared spaces too. If you manage an association building, a clubhouse-type room or any common area with an exit door, the same rules about free egress apply, and we can look at the hardware on request.
Tell us the street or corridor when you call. It helps us plan the visit and bring the right device and trim for the type of door you have.
How do heat, dust and canyon wind affect exit hardware here?
San Dimas sits in the inland valley, where summer highs run well above the coastal basin. Doors expand in late-summer heat, and latches that worked fine in spring start to bind. We hear about sticking latches in that season as a routine complaint, and with an exit device the effect is serious: a bar that does not fully retract or a door that will not close and catch.
Canyon winds also carry dust into exterior hardware. On a back door that faces open ground, grit works into the latch, the bar mechanism and the strike. Over time it wears the moving parts and gums up the action. A device that is cleaned and lubricated with the right product, and checked once in a while, lasts longer than one left alone.
If your exit door faces the sun, or you notice the bar feeling stiff in the afternoon but fine in the morning, mention it. That points toward expansion or alignment, and the fix may be a simple adjustment to the door, closer or strike rather than a new device. Our door closer repair work often goes hand in hand with these calls.

Call (213) 577-1366Why call Wilshire Lock & Key for exit devices?
We have been in business since 1987, and exit hardware is part of that history. We are one company with a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, so you are not handed to a dispatch middleman who has never seen your door. The person you talk to is part of the company that does the work. David, the owner and lead technician, oversees the work.
You should also check any locksmith you hire. California requires locksmith companies to hold a BSIS LCO license, and you are entitled to ask for the number. That is good advice no matter whom you call.
If your exit door is part of a bigger project, we can look at the wider picture: commercial door hardware throughout the building, or access control installation so the entry side is managed while the exit side stays free. We handle these as separate scopes and tell you what each one needs.
What should you do right now if an exit door is stuck or will not latch?
If the door will not latch and the building is open, the priority is keeping the exit clear and the door closed overnight. Do not chain it, wedge it, or lock a deadbolt over it as a quick fix. Those shortcuts block the exit and cause worse problems.
If you are locked out of your own business and the exit door is the only way in, see business lockout service instead. If it is an after-hours problem, our emergency locksmith page explains how we handle those calls, and our mobile locksmith vans come to you. Call (213) 577-1366 and describe what the bar or latch is doing. That description often tells us what to bring.
Frequently asked questions
What is the difference between a panic bar, a push bar and a crash bar?
They are mostly different names for the same thing: a horizontal bar on the inside of an exit door that releases the latch when pushed. Panic bar, push bar, crash bar and exit device all describe the same family of hardware. The real differences are in the latch type, such as rim, rod or mortise, and in features like alarms, fire ratings and outside trim.
Does my San Dimas business need panic hardware on its exit doors?
It depends on how the building is used and how many people it holds. The building department or fire marshal decides this, not us. We can install the hardware once you know what is required, and we will tell you if we see a door that does not look right for an exit. For the official answer, ask your local authority.
Can you repair my existing panic bar, or does it need to be replaced?
Often it can be repaired. Worn latches, loose trim, misaligned strikes and sticking bars are frequent fixes. Replacement makes sense when the device is bent, parts are no longer available, or it is the wrong type for the door. We look at it first and tell you which route is more sensible before we do anything.
Can a panic bar be added to a door that never had one?
Usually yes, but it depends on the door. Hollow metal, aluminum and wood doors each need a different mounting method, and some may need reinforcement. If the door is fire-rated, only hardware listed for that use can go on it. We inspect the door and explain what will work.
Can the outside of an exit door still be locked with a key?
Yes. Most exit devices can be fitted with outside trim, a lever or pull with a key cylinder, so staff can enter from outside while the inside stays free to exit. Some doors are exit-only and have no outside trim at all. Either way, pushing the bar from inside should always open the door without a key.
Why does my panic bar stick in the summer?
Heat makes doors expand, and San Dimas summers run hot inland. A door that rubs the frame or a latch that no longer lines up with the strike can stop the bar from fully retracting or the door from catching. Dust from canyon winds can also stiffen the mechanism. Adjustment, cleaning or a closer repair often solves it.
Can you service panic bars on fire-rated doors?
Yes, with care. A fire-rated door must keep its rating, so hardware has to be listed for that use, and we do not cut or drill in ways that break the label. If we cannot confirm a door's rating on site, we will say so and suggest checking with your building department.
Do you answer calls after hours for a failing exit door?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. Call, describe what the door is doing, and we will tell you how we can help. We will not promise a fix we cannot confirm over the phone, but we will tell you what we need to see.
