How much does patio door lock replacement cost?

Patio door lock replacement starts from $69, with the exact price confirmed after we see the door style and hardware. We give a free estimate over the phone before any work begins.

Can you make my sliding patio door more secure?

Yes. Beyond replacing the main lock, we can add a foot bolt or auxiliary latch, install an anti-lift block so the panel can't be lifted off its track, and fit a security bar or pin lock for a strong second layer of protection.

Do you fix French patio doors too?

We do. French patio doors take deadbolts or multipoint locks that secure the door top and bottom. We install the right hardware for your frame so both panels lock firmly.

My patio door latch won't catch — can you fix it?

Usually yes. A latch that won't catch is often a worn hook or a misaligned strike from a settled frame. We replace the hardware and realign the strike so the door locks reliably again.

How fast can you come out?

We confirm an arrival window when you call.

When a lock change makes sense

Moving into a home

You don't know who still has a key from before. New locks (or a rekey) put you back in control of every key that opens the door.

Worn or damaged locks

Keys that stick, cylinders that turn roughly, or hardware damaged after a break-in attempt — replaced with new, tested hardware.

Upgrading hardware

Stronger deadbolts, keyed-alike sets, or smart and keypad locks fitted to your existing door.

Rekey or replace?

Both retire the old keys. The right choice depends on the condition of your hardware.

Rekey

Keeps your existing locks in place
Old keys stop working
Good when hardware is in solid condition
Usually the lower-cost option

Replace

New lock hardware fitted and tested
Right choice for worn, damaged or dated locks
Lets you upgrade grade, finish or key type
Needed when parts are no longer available

"Jonathan was a true professional. He promptly arrived at my home to fix my door lock issue. I had stripped screws from a current door lock that needed to be removed, which he did very easily. In addition, he installed my new door lock for me. This all took under an hour."

"Jonathan was amazing to work with. He was super responsive, quick to schedule, and showed up right on time in Reseda. He made the whole process really easy and was very friendly and professional throughout. He rekeyed all three of our doors efficiently and gave us very fair pricing, which we really appreciated. On top of that, he went the extra mile to make sure we had copies of the new keys before he left. Overall, a great experience — highly recommend Jonathan if you need a reliable locksmith!"

"Jonathan did an amazing job doing a high-security lock fix in Sherman Oaks. He was very transparent with the costs. He also showed me exactly what was wrong with it and how he was going to repair it. Furthermore, he was very detailed in making sure everything was done correctly before leaving. Highly recommended."

"Amazing service! Responded to my inquiry quickly and made the trek over an hour to Van Nuys to come repair my stuck front door lock at 10pm on a Sunday night. Extremely fair pricing! The repair even came with a one year warranty."

More about this service

Patio doors are one of the most common weak points in a home's security. The factory latch that comes on most sliding glass and French patio doors is thin, easy to force, and often the first thing a burglar tests. Replacing that hardware with a proper lock closes an easy entry point that many homeowners overlook.

OE Lock & Safe replaces and upgrades patio door locks throughout Los Angeles County — from sliding glass door mortise locks to French-door multipoint hardware — so your back of the house is as secure as your front. Here's what you should know before upgrading your patio door lock.
