  • If the lease is in your name, it is your right to change the locks to your home whenever you want. Someone who is "subletting" can never change the locks on you under any circumstances
  • Your landlord can only change the locks on you once you have been evicted with a court order.
  • If you are in a situation where you have a squatter, please consult an attorney.
  • If you have been a victim of domestic violence you should get your locks changed immediately.

This illustration shows the multiple levels of a commercial grade master key system

In a master key system, each lock has its own key that opens only that particular door. There also exists a "master key" that opens all the locks in the system. As demonstrated above there can be multiple levels to a master key system depending on your needs. Master key systems are usually found in commercial environments, but can be applied in a residential situation as well. They are appropriate in any environment where you want to grant access to some doors and restrict access to others. We service all master key system types including Schlage, Sargent, BEST, Falcon as well as others.

With the key code on the front of the lock, we can make you a new set of keys even when you don't have them. Some are harder to read than others - this one for example is W469If you lost the keys to your filing cabinet or need to secure a filing cabinet that does not lock at the moment, we can help.

The most common (and affordable) way to make keys for your filing cabinet is by giving us the code off the front of the lock (where you put the key into.) This saves the cost of a technician coming to your location to make keys. You can call the key code numbers into our shop and pick them up - usually within the hour.

The most common reason for calling us is to change your lock cylinder - fitting new keys to your lock so the old ones no longer work. We proudly charge a $125 flat rate to change any lock. No matter what kind of deadbolt, door knob of any kind, Medeco, Mul-T Lock etc. we can re-key it for $125. This may sound higher than the $25 and below service call our competitors claim to charge, but once you are done with the hidden fees and items it will come out to as much as if not more than $125.


Think about it - how can anyone possibly stay in business charging only $25 for a licensed locksmith to drive to you in a company vehicle and provide you with quality lock or cylinder hardware? It is a scam.
