Fast, Reliable Rekey Locks Across El Cajon
Rekeying a lock in El Cajon typically costs $25 – $45 per cylinder for standard residential hardware, and most three-door homes are done in under an hour. That includes the written price before anyone is dispatched, the live arrival time you can track, and before-and-after photos so you can see exactly what changed. If you just moved into a place off Broadway, bought a rental near the 67, or lost track of who has keys to your Granite Hills home, call (409) 405-4485 and we’ll walk you through what it actually takes to make every old key stop working.
Our Rekey Locks team knows the housing stock here. A lot of it was built fast during the aerospace years, and that means doors with mismatched hardware, mortise bodies from the 1960s, and deadbolts added decades apart. We handle that. No lecture about replacing everything. Just a straight answer on what it costs to get one key working every door you own.
Why Preston Locksmith & Security Is El Cajon’s Preferred Rekey Locks Company
We’ve been doing this since 2008, and the thing El Cajon homeowners tell us they value most is the written price before any work starts. No hourly mystery, no bill that grows between the estimate and the invoice. The price you approve on the phone is the price on the invoice, period. Kevin Yoon leads our team, and the standard he set is simple: if the job isn’t done right, we make it right. That’s the 365-Day Done Right Promise, stamped in writing on every repair.
Our technicians are background-checked and arrive in uniform. You’ll get a live trackable arrival time through The Relay Visibility Guarantee, so you know who’s coming, what they look like, and when they’ll knock. Before-and-after photos are included on every job, and every rekey carries a written guarantee including a free second visit if anything fails. No voicemail trees either. A live person answers 24/7.
Rekey Deadbolt in El Cajon
A deadbolt rekey in El Cajon means pulling the cylinder, swapping the internal pins to match a new key, and reinstalling it so the old key no longer turns. On most homes here, that’s a Kwikset or Schlage deadbolt above a knob, and both get rekeyed to the same new key in one visit. Expect $25 – $45 per cylinder for standard hardware, with high-security brands like Medeco or Mul-T-Lock running higher because the cylinders themselves are more complex.
When a Deadbolt Rekey Is Urgent
Lost keys, a roommate who moved out, a rental turnover on Chase Avenue, or keys handed to contractors during a remodel. If you can’t account for every key, you can’t account for who gets in. A rekey is faster and cheaper than replacing hardware, and in most cases it’s done same-day in El Cajon.
Our Approach on Mismatched Hardware
El Cajon’s older tracts often have a deadbolt added years after the original knob. Sometimes it’s a KW1 keyway, sometimes SC1, sometimes both on the same door. We rekey both to one key so you’re not carrying two keys for one door. That’s standard practice for us, not an upsell.
Rekey House in El Cajon
Rekeying a whole house in El Cajon usually involves every exterior door: front, back, side, and often the garage entry. The flat per-cylinder range of $25 – $45 means a typical three-door house lands around $100 – $160, written in advance. We confirm the exact count before we dispatch, and we confirm it again at the door before any tool leaves the bag.
What a Whole-House Rekey Includes
Every lock cylinder gets rekeyed to one new key. We test each one in front of you, and we hand you the new keys with the old ones still in your hand, already dead. If any lock has a worn cylinder that won’t rekey cleanly, we tell you the replacement price in writing before touching it. You approve or decline. No surprises.
Renters, Landlords, and New Buyers
If you bought a house near Granite Hills or took over a rental off Main Street, you probably have no idea how many keys are floating around from previous tenants or sellers. We rekey every lock in one visit, and we can key the front, back, and garage to one key or split them out however you want. Landlords in El Cajon often set us up to rekey between every tenant, which we can schedule on short notice.
Trusted Brands We Service in El Cajon
We stock parts and cylinders for the brands El Cajon homeowners actually have on their doors: Kwikset and Schlage on most residential deadbolts, plus Yale, Baldwin, and Medeco on higher-end and older hardware. If your 1960s door still has a Baldwin mortise body, we don’t have to special-order a cylinder and make you wait. We carry what’s needed to rekey these vintage locks on the truck, which is part of why we can usually finish a whole house in under an hour.
Common Rekey Locks Problems We See in El Cajon Homes
- Mismatched vintage hardware on one door. A 1962 ranch off North Second Street might have an original mortise lock body and a newer KW1 deadbolt on the same slab. An untrained rekey leaves one key for the knob and another for the deadbolt. We rekey both to one key, every time.
- Big-box replacement cylinders failing in dry inland heat. El Cajon’s arid climate and hot summers eat through cheap cylinders that aren’t ANSI Grade 1. We see these fail within a year, and we stock proper replacements so you don’t get a second service call.
- Rental turnover keys everywhere. A house that’s been rented for five years has dozens of keys out there. Some landlords rekey only the front knob and leave a keyed-alike deadbolt above it untouched, which defeats the point. We check every lock, not just the obvious one.
- Worn cylinders on original 1960s hardware. Old Kwikset knobs and mortise bodies get sloppy. The cylinder still turns but the pins don’t seat reliably. We can often rekey them anyway, and we’ll tell you honestly when a cylinder is too far gone and show you the replacement price first.
Pricing for Rekey Locks in El Cajon, CA
Here’s what we charge in El Cajon, in plain numbers. Standard residential rekey: $25 – $45 per cylinder. A typical front door with a knob and a deadbolt: $50 – $90. A whole house with three exterior doors: roughly $100 – $160, confirmed in writing before we dispatch. High-security cylinders from Medeco or Mul-T-Lock start higher because the cylinder work is more involved. The number we quote on the phone is the number on the invoice.

FAQs About Rekey Locks in El Cajon
We rekey them. We pulled the mortise cylinder from a 1962 ranch off North Second Street not long ago, changed the pins to the homeowner’s new key, then rekeyed the knob to match so one key ran both. Total time was under 45 minutes, and the per-lock price was in writing before we rolled a truck. We only recommend replacement when the cylinder is genuinely too worn to hold pins, and we show you the price before touching it. Call (409) 405-4485 for an exact quote.
Yes. That’s a standard whole-house rekey for us. We rekey every exterior cylinder to one key, including the door from the garage into the house and often the garage door lock itself. Most El Cajon homes take under an hour, and we test every lock in front of you before we leave. We can also do split-key setups if you want the garage on a different key. Call (409) 405-4485 and we’ll confirm the lock count and total price before dispatching.
Usually under an hour, sometimes 45 minutes. The actual cylinder work is quick; what adds time is when hardware ages differently across doors. El Cajon’s older homes often have a mortise body on the front door and newer deadbolts in back. We plan for that, and we don’t charge extra for the mismatch. You’ll have a live arrival time and before-and-after photos through The Relay Visibility Guarantee. Call (409) 405-4485 for scheduling and an exact written price.
You’ll have a live trackable arrival time before we get there, so you know exactly when the tech is coming. The tech arrives in uniform, is background-checked, and will introduce themselves by name. You’ll also receive before-and-after photos of the work through The Relay Visibility Guarantee. If anything feels off, call our office and we’ll confirm who’s at your door in real time. We answer live, 24/7.
Usually yes. Many smart locks and keypad entries have a physical key cylinder as a backup, and that cylinder can be rekeyed just like a standard deadbolt. If you’re locked out of the app or the keypad dies, the physical key still has to work. We rekey the cylinder for the standard per-cylinder price, and we test the full lock function before we leave. If the keypad or motor is failing, we’ll tell you and show you repair or replacement pricing in writing. Call (409) 405-4485 for an exact quote on your specific lock.
