This page is for Los Angeles homeowners and business operators who already own Mul-T-Lock hardware and need it rekeyed, whether that’s after a tenant move-out in Silver Lake, a lost key in Koreatown, or a contractor dispute in Sherman Oaks. If you’re not sure whether your lock is a Mul-T-Lock or something else, we’ll identify it on arrival and tell you exactly what it’ll take.

How Mul-T-Lock Products Fail, and How We Fix Them

Mul-T-Lock makes genuinely good hardware. But Los Angeles locks see real use, and certain failure patterns come up again and again in the field. Here’s what we actually find when we open these up:

• Interactive+ cylinder telescoping pin wear. The Interactive+ uses a spring-loaded telescoping pin inside the plug. After years of daily use, that pin loses tension and the key starts feeling sloppy going in and out. We replace the pin set during the rekey, not just the top pins like a generic rekey would. It’s a 10-minute fix most L.A. locksmiths skip entirely.
• Classic Pro deadbolt timing drift. On the older Classic Pro line, the cam that throws the deadbolt can drift out of time after a few thousand cycles. The key turns fine but the bolt only half-throws. During a rekey, we inspect and retime the cam. If it’s too far gone, we tell you before ordering parts, not after.
• Keychain copy keys that never worked right. Mul-T-Lock keys use a telescopic pin system that big-box key machines can’t cut correctly. We regularly see homeowners in Echo Park and Highland Park carrying copies from a kiosk that work intermittently or stick. We cut proper OEM-profile keys after every rekey and test every one in front of you.
• Build-up in the pin chambers from coastal air. Westside neighborhoods like Venice and Marina del Rey put salt and moisture into door hardware constantly. Mul-T-Lock’s tighter tolerances mean that build-up binds pins that a looser Schlage or Kwikset would shrug off. We clean and lubricate every chamber during the rekey. It’s standard on our Mul-T-Lock jobs, not an add-on.
• Lost key card, no owner documentation. Mul-T-Lock cylinders ship with a plastic key card that controls who can order key copies. Lost keys plus a lost card used to mean replacing the whole cylinder. We can now decode and rebuild the cylinder without the card on most Interactive and Classic Pro models in Los Angeles, which saves you the cost of new hardware.

Our Mul-T-Lock Rekey Locks Process

1. 1
   You call (409) 405-4485. A live person answers, day or night. You describe the lock and the situation. We give you a real price range on the phone, not an hourly teaser.
2. 2
   You get a written price and a live arrival time. The Relay Visibility Guarantee means you can track our tech’s location before they arrive. No four-hour windows.
3. 3
   Diagnostics comes first. We inspect the cylinder, check the key, and test the throw. If we find something beyond the rekey scope, you get a clear explanation and a new written price before anything else happens.
4. 4
   We open the cylinder and start the pin work. We decode the old key, remove the old pins, and build the cylinder to the new key’s cut. For Interactive+ models, that includes the telescoping pin inspection and replacement when needed. OEM pins are standard. Aftermarket pins are fine for standard Mul-T-Lock cuts, but if we don’t like what we see in the cylinder, we say so.
5. 5
   Before-and-after photos, key testing, and a walk-through. Every new key gets inserted and turned twice in each lock while you watch. We photograph the work, hand you your keys, and send a digital invoice with a pay link before we leave.
6. 6
   The 365-Day Done Right Promise kicks in. If the rekey fails within a year, we come back and fix it free. That’s a written guarantee on every job, not a verbal promise.

Why Los Angeles Homeowners Call Preston Locksmith & Security for Mul-T-Lock Work

Kevin Yoon grew up in Koreatown and learned lock work hands-on through the vocational program at Los Angeles Trade-Technical College. He’s been rekeying Mul-T-Lock cylinders in this city for years, and the reason he does it the way he does is simple: his mother got burned by a bait-and-switch locksmith, and he decided nobody in this city should get handed a surprise bill at the door again. Real price on the phone. Same price at the door. That’s it.
