Need old keys to stop working, or a lock that closes reliably? MT Lock & Key Services provides mobile lock rekeying, lock replacement and repair in Sherman Oaks for homes and businesses. Tell us how many locks need attention and whether you have a working key. We will discuss the options, availability and an estimate before arranging service.
We come to your property. This is a mobile service, with no walk-in customer location.

Start with access, then assess hardware condition
Gather the keys supplied at handover and work out which entrances they operate. List the locks you want changed, including a separate workspace if it is within your authorized scope. A lock that functions well may be suitable for rekeying, while damaged hardware or an incompatible keyway may require another approach. Explain whether you want compatible entrances to share one key. Once the work is complete, check each affected door and decide how the new keys will be distributed; keep spare-key arrangements with people you authorize.
Rekey or replace your Sherman Oaks locks?
- New keys, working hardware: rekeying compatible cylinders can stop the old keys from operating the locks included in the work. This can be useful after moving in or losing a key.
- Sticking, damaged or unreliable hardware: describe the problem so we can assess whether repair or replacement is appropriate. A door or strike alignment problem may need attention as well.
- One key for several doors: ask whether your locks are compatible. Different brands or keyways may prevent a single-key setup without hardware changes.
Lock changes for offices, shops and rental properties
For a Sherman Oaks business or rental turnover, list each entrance and the people who should keep access. Tell us about existing master keys before any cylinders are changed. We can discuss commercial lock service alongside your home or rental needs, with the final scope approved by an authorized owner or manager.
Before your service visit
- Bring the existing working keys if you have them.
- Identify every entrance whose old keys should stop working.
- Mention locks that stick, loose handles or doors that need lifting to latch.
Rekeying, replacement and other locksmith help
Rekeying changes which keys operate compatible locks; replacement changes the hardware. Ask us to assess the condition and explain the options. Explore our residential and commercial locksmith services, or read the rekeying and replacement guide.

Questions before booking
Is rekeying useful even if the seller returned all keys?
If you want certainty that the previous keys no longer operate the changed locks, discuss rekeying. Returned keys do not establish whether copies exist.
Can I retain a lock that works well?
Compatible hardware in good condition may be rekeyed rather than replaced. The cylinder and condition need to be assessed first.
What affects the estimate for rekeying or replacement?
The number and type of locks, their condition, access to the property and any replacement parts can affect the estimate. Ask whether the visit, labor, parts and other applicable charges are included. Inspection may be needed to confirm the final scope.
Can you help if I am locked out and need the keys changed?
Tell us that you need both entry assistance and a key change. Opening the door and rekeying or replacing a lock are separate parts of the job, so ask for both to be included in the scope and estimate.
