HOME REKEYING SERVICES
Change the keys that work in your home locks.
Rekeying changes a compatible lock cylinder to work with a different key. The old keys stop operating that cylinder while suitable existing hardware stays in place. Tell us which doors and locks you want included.

New-home rekeying
Review the locks after moving in when you cannot account for keys held by previous occupants.

Lost or stolen keys
Change the keys for affected compatible locks when a missing key could still provide access.

Roommate and tenant changes
Update suitable locks when someone moves out or a residential tenancy changes, with the owner's authorization.

WHEN TO REKEY HOME LOCKS
Rekey Locks After a Move or Lost Keys
A lock can work normally while its keys are still in the hands of someone who no longer needs access. Moving, losing a key, and changes in a household are useful times to review the doors involved and decide which cylinders need a new key.

01
Moving into a home or rental
02
Lost keys or unknown spare copies
03
A roommate or tenant moving out
04
Temporary key holders no longer need entry
05
Different keys complicate everyday access
Make a list of the doors and key holders before arranging service. If you would also like to change how people enter, compare keypad lock installation with rekeying the existing locks.
REKEYING OR REPLACEMENT
Should You Rekey or Change Your Home’s Locks?
Rekeying changes the keys that operate compatible existing locks. Lock replacement changes the hardware. If the lock is in good working condition and your goal is to stop old keys from working, rekeying may be suitable. Worn, damaged, or unsuitable hardware may need repair or replacement instead.
After a move or lost keys, ML Locksmith assesses your home locks and explains which approach fits their condition and your access needs. If you also want several doors to use one key, we check whether their cylinders and keyways are compatible.
Compare home lock changes and upgrades if you need different hardware as well as a change of keys. For an office, storefront, or managed business property, see commercial rekeying.

LOCK COMPATIBILITY
Matching keys depends on the hardware already fitted.

01
Compatible keyed residential deadbolts
02
Suitable keyed knobs and levers
03
Cylinder condition and serviceability
04
Compatible keyways for shared-key plans
05
Specialty hardware assessed separately
Different locks cannot always be arranged to use one key. Photos of the locks and their markings help us discuss compatibility. French doors and multipoint hardware need an assessment of their particular locking system rather than an assumption that every cylinder can be rekeyed.
AFTER THE KEY CHANGE
Put a practical household access plan in place.

01
Decide who receives the new keys
02
Keep a record of spare-key holders
03
Set aside an appropriate backup key
04
Review temporary access after work ends
05
Check each agreed lock with its new key
Rekeying updates the agreed cylinders, so confirm that every intended door is included. For supported app-based access and guest features, see smart lock installation. Our residential locksmith services cover other home lock and hardware needs.

Yes. ML Locksmith provides commercial locksmith services for offices, storefronts, businesses, and managed properties, including rekeying, lock changes, lock installation, lock repair, master key systems, high-security locks, door closers, and panic/exit hardware. We also help with office and business lockouts.
We diagnose, repair, and replace French door locks and multipoint locking hardware, including three-point mechanisms and Hoppe systems. We also service patio and sliding-door locks.
Repair or replacement depends on the mechanism’s condition and compatible parts. When you call, describe the symptoms and any brand markings on the hardware.
Many home locks can be rekeyed when the existing hardware is in good condition, allowing you to change which key works without replacing the entire lock. We also repair and replace residential locks and install compatible smart and keypad locks.
For electronic locks, changing access codes is separate from rekeying a keyed cylinder. Pricing depends on the hardware, work, and location; call to discuss the service and cost before work begins.
