Master Lock Locksmith Service in San Luis Obispo
Master Lock makes security products for homes, businesses and everyday storage. Its familiar products include keyed and combination padlocks, along with other locks and security devices. Many are portable locks that secure a gate, storage space or equipment rather than a fixed door lock.
That distinction matters when you call us. We first identify the kind of Master Lock product and how it is fitted, then match the service to it. We come to your San Luis Obispo location, whether the issue is a misplaced key, a lock that will not work smoothly or a lockout. For a fixed door lock, the door and existing lock setup also affect which repair or replacement will fit.
- Rekey the existing lock — Rekeying changes which key operates a compatible lock without replacing its body. It can suit you after a key is lost or access needs to change, provided the particular Master Lock can be rekeyed. Our lock rekeying service starts at $55 per lock.
- Repair the lock — Choose repair when the lock is still suitable for the door or equipment but a key or internal mechanism is sticking, worn or not operating as it should. We inspect the lock’s condition and determine whether a repair can restore its use. Master Lock repair starts with identifying the lock type and the source of the problem.
- Replace the lock — Replacement fits when the lock is damaged beyond practical repair, no longer suits the way you use the space, or cannot be rekeyed to meet your needs. For a door installation, we check how the replacement will fit the existing door before installing it. A lock change starts at $85 plus hardware.

Where Master Lock Products Fit Around Your Property
Rental property
A Master Lock padlock can secure a storage area, gate or other space where a portable lock is a better fit than changing a door lock. After a tenant or keyholder change, ask whether the existing lock can be rekeyed or should be replaced.
Family home
For a home, the right product depends on what you need to secure. A padlock may suit a gate or storage area, while a fixed door calls for hardware made to fit that door. We look at the use and existing setup before recommending repair, rekeying or installation.
Office or storefront
Businesses may use portable locks for storage, gates or equipment, while doors need hardware suited to regular entry and exit. A lock that is difficult to operate can interrupt access, so we check its condition and intended use before working on it.

Getting a Copy of a Master Lock Key
A copy of a Master Lock key may be straightforward when the key is an ordinary type and the lock accepts a standard duplicate; some keys or systems may have restrictions on who can have copies made. Keep any original keys, key tags and product information you have, because they can help identify the correct lock and key type. For Master Lock key replacement, we check what lock the key belongs to and whether it needs a duplicate, a replacement key or service to the lock itself.

Frequently asked questions
Can you install a Master Lock product on my existing door?
Yes, we can assess the existing door and the Master Lock product you want installed. Fit depends on the product’s design and the door’s current preparation, so we check those details before installation rather than treating every lock as a direct fit.
Can you rekey a Master Lock without replacing it?
Yes, when the specific lock is designed to be rekeyed and its condition allows the work. We identify the lock first; if it is not compatible with rekeying, replacement may be the appropriate service.
What should I do if I’m locked out with a Master Lock?
Call (805) 977-6159 and tell us where you are and what type of Master Lock is involved. We provide mobile locksmith service in San Luis Obispo, and the service call is $29; lockouts start at $55.
Can you find a replacement part for an older Master Lock?
We inspect the lock and identify the part or function that has failed. If a compatible part cannot be matched, we can replace the lock instead; having the old key or product information available can help identify it.
Can you make all the doors in my San Luis Obispo home work with one key?
We check whether the existing locks can be keyed alike and whether they are compatible with one another. If they are not, replacing some locks may be needed to create a working setup for the doors you want to match.
