The door clicks shut behind you, the keys are on the kitchen counter, and the spare is somewhere you can’t reach. Prime Locksmith Services gets St. Louis homeowners and renters back inside quickly and calmly, using picks and bypass tools that open the lock without drilling it or damaging the door.
We handle knob locks, deadbolts, keypad locks and sliding doors on houses, apartments, condos and townhomes. If your keys are lost for good, we can re-key or change the lock on the same visit, so the old keys stop working.
For house lockout service in St. Louis or any job for a residential locksmith in St. Louis, call (314) 745-4590.
A simple process that keeps your home secure.
Tell us the type of lock and whether the keys are inside or lost.
We quote the lockout on the phone, so you know the cost upfront.
Photo ID with the address, a lease, a utility bill or mail addressed to you once inside.
We pick or bypass the lock. Drilling is a last resort, and we tell you before we do it.
If keys are lost, we can re-key or replace the lock before we leave.
If a child is alone inside, someone needs medical help, or food is burning on the stove, call 911 right away. Emergency crews can force entry immediately. We can repair or replace the lock afterwards.
