What actually makes a lock 'high security'?
A high security lock is a cylinder, deadbolt or lock body built to resist the specific ways ordinary locks get beaten: picking, bumping, drilling, forced turning and unauthorized key copying. The phrase gets printed on a lot of packaging, so it helps to know what is really behind it before you pay for it.
A genuine high security cylinder usually combines several features. A standard builder-grade cylinder usually has few or none of them.
The point is not that any lock becomes impossible to defeat. The point is that defeating it takes more time, more skill and more noise, and that the key itself is controlled. That is what you are buying when you upgrade.
- Tighter machining tolerances, so there is less slop for a pick or bump key to exploit
- Security pins, such as spool or serrated pins, that bind and false-set when someone picks the lock
- A more complex keyway or a sidebar mechanism that a basic pick set cannot reach
- Hardened steel inserts placed where a drill bit would normally go
- A restricted keyway, so duplicate keys are cut only with proper authorization
Why do Bell Gardens homes and buildings ask about high security locks?
Bell Gardens is a dense city. Most of the housing is small, pre-1960 single-family homes and low-rise apartment complexes, and renters make up the majority of households. That mix shapes what we see on locks. Many older bungalows still carry decades-old knob-and-deadbolt hardware, and nobody remembers how many copies of those keys exist. A set of keys that has passed through several tenants, relatives and contractors is a real weakness no matter how good the door looks.
People usually call us about high security locks for one of a few reasons: a break-in or attempted break-in, a landlord who wants key control across several units, a business that wants stronger cylinders on a storefront, or a homeowner who read about bump keys and wants to know whether their lock is vulnerable. Sometimes the honest answer is yes. Sometimes the answer is that the cylinder is fine and the door frame or strike plate is the actual weak point.
We would rather tell you that on the phone than sell you a cylinder you do not need. If you are weighing options, we can talk through the door, the frame and your keys before anyone drives out.
How we handle a high security lock installation, step by step
Whether we come to you with a mobile van or you stop by our Westwood storefront at 10740 Wilshire Blvd, the process is the same. We do not swap hardware until we have looked at what the door can support.
- You call (213) 577-1366. Someone answers, day or night, and we ask what door it is, what lock is on it now and what prompted the call.
- We look at the whole door, not just the cylinder: the door material, the frame, the strike plate, the screws that hold it, and whether a security door or screen sits in front.
- We explain your options in plain terms. That includes which features address which threat, which products suit your door, and whether the lighter-cost route, such as upgrading only the cylinder, is enough.
- We agree on the scope before work starts, so you know what will be installed and what will be left alone.
- We install the cylinder or deadbolt, set the strike properly, and where the frame is weak we reinforce it or tell you plainly that it needs attention.
- We test the lock repeatedly with the door open and closed, hand you the keys, and explain the key-control rules for your restricted keyway, including who can order copies.

Call (213) 577-1366Pick-resistant, bump-resistant and drill-resistant: what each one protects against
These terms get blurred together, but they describe different defenses. Knowing the difference helps you choose, and helps you spot a vague product claim.
Most good high security cylinders layer several of these. Cheap products often advertise one and quietly skip the others. If you are comparing, ask which of these a given cylinder actually addresses, and ask for the grade rating on the lock body or deadbolt as well. A strong cylinder in a weak deadbolt body is still a weak lock.
- Pick-resistant locks use security pins and tight tolerances so that ordinary picking tools give false feedback and take far longer to work. They are built to slow down a skilled attacker and to defeat an unskilled one outright.
- Bump-resistant locks change the pin design or add secondary elements so that a bump key does not transfer enough energy to line up the pins at once. Standard cylinders are the ones most exposed to this.
- Drill-resistant construction places hardened inserts in the cylinder and lock body so a drill bit skids or stalls rather than cutting through the shear line.
- Key-control systems add a restricted blank and an authorization process, so copies cannot be cut at a hardware store counter.
How much do high security locks cost in Bell Gardens?
We do not quote numbers in an article because the real figure depends on your door and your goals. What we can do is tell you exactly what moves the cost up or down, so you are not surprised.
On an installation, the lighter-cost route is often replacing only the cylinders in hardware that is already sound. That keeps your existing deadbolt bodies and uses the stronger cylinder inside them. It is usually the more economical way to add pick and bump resistance. If the existing hardware is worn or low-grade, replacing the whole deadbolt makes more sense and costs more.
Because we are a storefront with our own mobile vans, we can give you a clear scope when you call and a firm number once we have seen the door. If anything changes on site, we say so before continuing.
- The number of locks: one front door, or every entry in a small building
- Whether you need cylinders only or complete deadbolts and lock bodies
- The level of key control: a restricted keyway with authorization rules costs more than an ordinary keyed-alike set
- Door and frame condition: reinforcement, a new strike or a repaired jamb adds labor and materials
- Door type: wood, metal, a security door in front, a storefront door or a mobile home door each take different hardware
- Number of keys, and whether several locks need to be keyed alike
- Time of day and where you are: after-hours calls and distance from our base can affect the service charge

Call (213) 577-1366Restricted keys, landlords and who controls the copies
The key itself is half of high security. A pick-resistant cylinder does little good if anyone can duplicate its key for a few minutes of effort at a counter. Restricted keys are cut from blanks that are not sold openly, and copies require authorization from the person on record. That is the main difference between a high security system and an ordinary one.
This matters a great deal in a city with a strong renter majority. When tenants turn over in dense multi-unit blocks, a landlord has two choices: keep tracking an unknown number of old keys, or change what the key fits. For routine turnover, rekeying is often enough. For properties where key control is a recurring problem, restricted cylinders let an owner decide who can authorize copies. If you manage rentals, our page on locksmith services for landlords covers how we work with owners across multiple units.
If you need extra keys for a restricted system, we handle that too, and we ask who is authorized first. Ordinary copies are covered under key duplication, but a restricted key is a different process, and we explain it before you commit to the system.
Why call Wilshire Lock & Key for high security locks?
A high security installation should be done by someone who will still be around to service it. We have been in business since 1987, and David, the owner and lead technician, oversees the work. He is the person who decides what we recommend and how we install it.
We are one company. We have a storefront at 10740 Wilshire Blvd in Westwood and our own mobile vans, so when you call (213) 577-1366 you reach us, not a national call center that dispatches the nearest available contractor. No middleman means the person who explains the options is working for the same company that does the install.
Our phones are answered 24 hours a day, every day of the year. You do not need to wait until morning to ask a question after a break-in or when you are locked out and want to plan the upgrade right away. We serve 140 cities across Los Angeles and Ventura counties, and Bell Gardens is about 21 miles from our base, so we are used to making the trip.
One more point worth knowing: California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for that license information before they work on your locks, including us. A company that hesitates to answer is telling you something.

Call (213) 577-1366High security locks across Bell Gardens: what we see locally
Bell Gardens covers a small footprint and almost all of it sits inside ZIP code 90201. The kinds of doors we work on vary a lot from block to block, so a single product is rarely the right answer for the whole city.
Along the Eastern Avenue corridor and near the Bicycle Casino district, a lot of the demand is commercial: storefront doors, back doors, roll-up gates and small offices. Storefronts here tend to want stronger cylinders on rear and side entries and tighter key control for staff turnover. If you run a shop on Eastern, the lock on the rear door usually matters more than the one on the front. For larger buildings with several doors, our commercial locksmith service can help plan the whole system.
Along the Garfield Avenue and Florence Avenue corridors, the housing is mostly the older bungalows and low-rise apartment buildings described above. Upgrading the front and rear deadbolts to pick-resistant and bump-resistant cylinders is the typical job. Because security doors are common here, we also check that the security door latch and the main door lock work together and that neither blocks the other. In apartment complexes near Bell Gardens High School, owners often ask us to bring the entry doors of several units onto one restricted key system, so a single authorized process controls the copies.
Mobile homes in the city's parks, including the historic park around the Gage Mansion, have lighter doors and different hardware than a standard house. A high security cylinder helps, but the door itself may limit how much protection the lock can add. We assess that on site and recommend what fits, which sometimes means a new deadbolt installation designed for that door.
The climate matters a little too. Bell Gardens sits in an inland basin with hot, dry summers, several degrees warmer than the coast. Heat makes doors and frames expand, which can cause tight or sticking locks, and a precision cylinder can feel stiff if the door is binding. Coastal corrosion is not a concern here, so we do not need to push special finishes for salt air. We check door fit while we are there, because a lock that fights a swollen door will wear out early whatever its rating.
What a high security lock will not do
No lock stops a determined attacker with unlimited time and tools. A glass panel next to the door, a hollow-core door, a loose frame or a short strike screw can all be defeated without touching the cylinder. High security hardware works best as part of a door that is sound, a frame that is anchored and keys that are controlled.
If you want to add convenience on top of that, we can discuss smart lock installation, though a smart lock is a different category and is not automatically more secure than a good mechanical one. If your current lock is simply worn out or damaged, the better starting point may be lock replacement or a visit from our mobile locksmith team to look at what is failing. We will tell you which one applies.
Frequently asked questions
What is the difference between a regular lock and a high security lock?
A regular lock has basic pin tumblers and an openly sold key. A high security lock adds features such as security pins, tighter tolerances, hardened drill-resistant parts and a restricted keyway, so it is harder to pick, bump or drill and harder to copy a key for.
Are pick-resistant locks really pick-proof?
No. Pick-resistant means the lock takes much more skill and time to open that way, not that it cannot be opened. Any honest locksmith will say the same. The goal is to make picking impractical for most people and slow for skilled ones.
Do I need bump-resistant locks for my Bell Gardens apartment or house?
If your door uses a standard cylinder, it is exposed to bump keys, and a bump-resistant cylinder closes that gap. Whether it is the first thing to fix depends on your door, frame and strike plate. We look at those at the same visit and tell you plainly where the weak point is.
Can you upgrade just the cylinder, or do I need a whole new deadbolt?
Often only the cylinder needs changing, and that is usually the more economical route. If the deadbolt body is worn, low-grade or poorly fitted, we recommend replacing the whole unit. We decide after seeing the hardware.
Can you make all my locks work with one key?
Yes. High security cylinders can be keyed alike so one key opens every lock you choose. We discuss the tradeoff with you, since a single key also means one lost key affects every lock it opens.
Why can't I copy a restricted key at the hardware store?
Restricted keys are cut from blanks that are not sold openly, and copies are authorized by the person on record. That is the point of the system, since it stops unknown copies from being made. We help you set up who is authorized.
Do you install high security locks on storefronts and commercial doors?
Yes. We work on storefront doors, rear entries and small offices, and we can plan stronger cylinders and key control for businesses. For bigger systems we can also advise on hardware beyond the cylinder, since it is a different scope from a residential job.
Can high security locks be installed on a mobile home door?
Often yes, but the door and frame set the limit. Some mobile home doors are light, so we check what the door can support and recommend hardware that fits it, rather than putting a strong cylinder in a door that cannot hold it.
Can I call about high security locks at night or on weekends?
Yes. We answer (213) 577-1366 every hour of every day, all year. You can ask questions, describe your door, and plan the visit whenever it suits you.
How do I know a locksmith is legitimate?
California requires locksmith companies to hold a BSIS LCO license. Ask for the license information before any work begins, and be cautious with anyone who avoids the question or will not tell you the company name on the phone.
