High Security Locks in Covina, CA

What actually makes a lock high security?

The phrase gets used loosely, so here is how we use it. A high security lock is built to resist the quiet ways a lock gets beaten, not just the loud ones. A standard builder-grade cylinder has loose tolerances and simple pins. A skilled person with a pick set, or someone with a bump key from a hardware-store kit, can open many of them in seconds. A high security cylinder tightens those tolerances and adds features that make picking and bumping far harder.

Three things separate a real high security lock from a regular one with a fancy box. The first is the cylinder: security pins, tighter machining, and often hardened inserts that resist drilling. The second is the key: many high security systems use a restricted keyway, which means blanks are not sold over the counter and copies need authorization. The third is the hardware around the cylinder: the strike plate, the bolt, the screws, and the door frame it all bolts into.

We say pick-resistant and bump-resistant on purpose. No lock is pick-proof, and anyone who tells you otherwise is selling something. What a good cylinder does is raise the skill, time, and noise an attacker needs, and that is often enough to make them move on.

• Pick-resistant cylinders use security pins and tighter tolerances to frustrate picking tools.
• Bump-resistant designs add features that defeat the bump-key trick that works on many ordinary locks.
• Restricted keys cannot be casually copied, which keeps track of who holds access.
• Hardened components resist drilling and forced entry at the cylinder.

Why do Covina homes and businesses ask for high security locks?

Most calls we get about this start the same way. Someone has moved into a place and does not know who still has a key. Someone has had a break-in nearby and wants the front door to be the hard one on the block. Or a property owner has a dozen doors and a drawer full of copies that nobody can account for.

In Covina the housing mix shapes the question. Older Craftsman-era and early-20th-century homes near the citrus-era downtown often still carry original or very old hardware, and the lock is the weakest thing on an otherwise solid door. The 1950s and 1960s ranch tracts around them were typically fitted with basic builder-grade deadbolts that have been in service for decades. Covina Hills has larger, semi-rural lots, many with gated driveways, where the house door is only one of several points to secure.

If you have lost a key, had a roommate or tenant leave without returning one, or simply never changed the locks after buying the property, a high security cylinder solves a control problem as much as a break-in problem. You decide who can make copies, and that is a different kind of protection than a thicker bolt alone.

How do we install high security locks, step by step?

We keep the process simple and we explain it before we drill or unscrew anything. The aim is a lock that suits the door and the way you use it, not the most expensive item on the shelf.

1. Call (213) 577-1366 and tell us what you are securing: a front door, a back door, a gate, a storefront, or several doors. Someone answers at any hour.
2. We ask about the door: material, thickness, existing hardware, and whether it sticks or binds. This helps us bring the right parts in the van.
3. On site, we inspect the door, the frame, and the strike. A strong cylinder in a split frame or a loose strike is a weak point, so we check those first.
4. We explain the options for your situation: a high security cylinder in your existing hardware, a full high security deadbolt, or a restricted-key system if you want key control.
5. We install the hardware, reinforce the strike and screws where the door needs it, and set the bolt so it throws cleanly without forcing.
6. We test every key and the full operation of the lock with you present, and explain how key copies work on your system and how to order more if the system allows it.
7. If you want, we can leave the old cylinders rekeyed or retired so nothing from the previous setup is still floating around.

Which types of high security locks do we install?

The right product depends on the door and the risk. Here are the main categories we work with, described by what they do rather than by brand.

• High security deadbolts for front and back doors, built with hardened bolts and reinforced cylinders. If you only need a standard replacement bolt, our deadbolt installation page covers that separately.
• Pick-resistant and bump-resistant cylinders that can often be fitted to hardware you already own, which is usually the more economical route when the lock body is sound.
• Restricted-keyway systems, where duplicate keys require a card or authorization and cannot be cut at a typical kiosk. For how copying works in general, see our notes on key duplication.
• Commercial security locks for storefronts, offices, and back-of-house doors, including heavier-duty cylinders and hardware built for constant use.
• Gate and driveway hardware with weather-resistant, tamper-resistant locking, which we handle with our gate lock repair work when a gate needs repair rather than a security upgrade.
• High security cylinders in keyed-entry parts of a smart lock setup, where the electronic side and the mechanical key backup both matter. If you are weighing electronics, our smart lock installation page explains that side.

How much do high security locks cost in Covina?

We do not quote numbers on a web page because the honest answer depends on your door. Here is what moves the cost, so you can judge a quote when you get one.

The biggest factor is the product. A pick-resistant cylinder dropped into your existing deadbolt is a lighter-cost option than a full high security deadbolt with a reinforced strike and a restricted-key system. A restricted keyway adds cost because the cylinders and the key control come with controlled distribution and slower, more deliberate copying.

The second factor is how many doors you are securing. Rekeying or replacing several locks to a single restricted key is usually more economical per door than doing them one at a time on different visits, and it means one key opens everything you want it to. If that is your plan, our lock rekeying page explains how that process differs from replacement.

The third factor is the door itself. If the frame is cracked, the strike is loose, or an older wood door has swollen and no longer lines up, the lock will not perform as designed until that is fixed. We tell you up front if the door needs work, and we separate that from the lock cost so you can see each piece.

Finally, timing and location play a part. Evening, weekend, and holiday calls take more of our team's time, and Covina is about 32 miles from our Westwood storefront, which is part of how we plan the trip. We will tell you the full cost before we start work, not after.

Why call Wilshire Lock & Key for high security work?

We have been in business since 1987, and that is a long time to learn which locks hold up and which ones only look good in a catalog. We work from a real storefront at 10740 Wilshire Blvd in Westwood and run mobile service vans, so you are dealing with an actual local shop and not a call center.

We are one company. There is no dispatch middleman who takes your call and sends a stranger you have never heard of. The person who answers works for the same business that comes to your door. David, the owner and lead technician, oversees the work and decides what is worth recommending and what is not.

California requires locksmith companies to hold a Locksmith Company license, known as an LCO license, issued by the Bureau of Security and Investigative Services (BSIS). It is smart to ask any locksmith for that license number before they start work, including us. High security locks are about trust, and you should be able to check who is handling your keys.

We will also tell you when a high security lock is not what you need. If your door is the real problem, or a rekey does the job, we will say so.

Where in Covina do high security locks make the most difference?

Covina is not one kind of place, and the right lock for one block is wrong for the next. Here is how we see it across the city, using the areas our customers actually call from.

Near downtown Covina and the Citrus Avenue district, a lot of the housing is older. Early-20th-century doors on the older blocks often have original mortise hardware or worn-out cylinders, and owners want better security without destroying the character of the door. That is a hardware-upgrade job: we fit a pick-resistant cylinder or a well-matched deadbolt, and reinforce the strike so the lock is actually tied into the frame. Heat matters here too. Covina has hot, dry summers, and older wood doors can swell and bind seasonally. A high security bolt that has to be forced to throw will wear fast, so we check the fit and adjust alignment as part of the job rather than leave it for you to discover in July.

Also in the downtown Citrus Avenue district, storefronts and restaurants need commercial-grade cylinders that stand up to daily use and tighter key control. A restaurant with turnover in staff is a good candidate for a restricted key system, since you can control who holds a copy. For larger setups with multiple doors and staff levels, a master key system can sit on top of high security cylinders, and our commercial locksmith page covers wider business needs.

In Covina Hills, the larger semi-rural lots and gated driveways change the picture. The front door matters, but so do side doors, garage entries, and the gate. We often see owners start with the main house door and then ask about keying everything alike so they carry one restricted key instead of a ring of them.

Along the Arrow Highway corridor and parts of Azusa Avenue, apartment complexes bring a different need. Landlords and property managers want to rekey units between tenants and control who can copy a key. A restricted keyway helps because a former tenant cannot just run a copy at a kiosk. If you manage rentals, our page for locksmith services for landlords covers the turnover side of that work.

We serve addresses across ZIP codes 91722, 91723, and 91724, and that includes Charter Oak, the adjacent unincorporated area with Covina addresses. Wherever you are, the first question is the same: what is the door made of, and what are you trying to protect?

What should you check before you buy a high security lock?

Whether you work with us or not, a few checks save money and frustration.

First, look at the door and frame. Press on the frame near the strike. If it flexes or you see cracks, the frame needs attention before the lock matters. Hollow-core interior doors are not suitable for exterior security hardware at all.

Second, ask what the lock is actually rated for. Standards exist for this: ANSI/BHMA grades measure durability and strength of residential and commercial locks, and some cylinders are tested for pick resistance. Ask which standard a product meets, and be wary of vague claims like military-grade.

Third, understand the key system. If the keys are restricted, ask how you order more, how long it takes, and who has to approve it. Restricted keys are a benefit, but only if you can still get a copy when you need one. Make sure you keep your authorization card or paperwork somewhere safe.

Fourth, think about the whole property. A strong front door does little if the back slider or the side gate is easy to defeat. We can talk through the weak points even if you only want one door done today.

Can we also help with the rest of the lock work?

High security locks are one part of the picture, and we stay focused on them here. If you also need emergency entry, broken key removal, car work, or a business lockout, those have their own pages and the same phone line. For a general overview of what we do in the city, start at our Covina locksmith page, then call (213) 577-1366 for anything specific.
