Changed staff, lost a key or moved into a property? MT Lock & Key Services provides mobile commercial and residential lock rekeying, replacement and repair in Van Nuys. Tell us which doors are involved, who should retain access and whether any lock is damaged. We will discuss the scope, availability and an estimate for your property.
We come to your property. This is a mobile service, with no walk-in customer location.

Map out the doors and access you need
Identify entrances used by all authorized staff and doors intended for a smaller group. Explain any existing master-key arrangement before changing individual locks. Do not assume a single-key setup is suitable for every door: convenience and the access you want to preserve should be considered together. List missing keys and unreliable hardware separately. During the appointment, have an authorized decision-maker available to confirm the final scope and new key quantities, then test the affected doors and keys before the visit is complete.
Commercial rekeying or lock replacement in Van Nuys?
- Employee turnover or a missing key: identify every cylinder the old key operates. Rekeying only one door may leave other entrances accessible with that key.
- Keep an existing master-key arrangement: explain which doors and users it covers before work starts. We will assess compatible options for the hardware.
- A lock that sticks or will not secure: request an assessment of the lock, door and alignment. Rekeying changes keys; it does not repair worn or damaged hardware.
Home rekeying after a move or lost keys
We also help Van Nuys homeowners reset access after a move, a lost key or a change in occupants. Gather any working keys and count the exterior locks you want assessed. Compatible locks in good condition may be rekeyed; damaged or unsuitable hardware may need replacement. See our residential locksmith services for more home security options.
Before your service visit
- List the doors included and which users should access each.
- Mention master-key arrangements or specialist commercial hardware.
- Choose the person who can approve changes and accept the new keys.
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
Can one missing key be the reason to rekey several doors?
If the missing key operates those doors and should no longer provide access, discuss all affected cylinders as part of the scope.
Can you work on a home as well as an office?
We provide both residential and commercial mobile service. Give the property and hardware details for each request so the right scope can be confirmed.
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 when all my car keys are lost?
Ask us to confirm service for your vehicle before a visit. Share the year, make, model, location and whether the vehicle is accessible. An all-keys-lost job can require different parts and programming from making a spare; Tesla key services are excluded.
