If you are having problems getting your key in and out of your lock…. your lock may just need a little lube. We HIGHLY recommend Triflow. Triflow is a teflon based lubricant that is great for locks. Spray a little Triflow into the keyway (where the key goes into the lock). Then take your key and slide your key in and out several times to make sure the lock is fully lubed. If that takes care of your problem… hold your call to us…. your problem is solved. If lubing your lock doesn’t help you may have a bigger problem so pick up the phone and call A-Locksmith- Craig so we can fix your problem.
