Locksmith in MillikenVintage hardware,cared for properly

On a door people leave through while the building is occupied, the door needs to open from inside with one motion and no key, so a key-both-sides bolt is not the right tool there. Security is added instead with a heavy-duty exit device and a reinforced strike, a keyed trim outside, an alarm contact, or a door position sensor on the access system, all of which keep the way out clear.

Sometimes, and the visit answers it. A key that failed from its own fatigue in a clean, smooth cylinder says nothing against the lock. A key that broke because the pins were worn flat, the cap had loosened or the keyway was full of grit says the cylinder needs a service or a rekey. One that broke in a corroded, pitted plug is telling you the lock is due for replacement.

Treat it as two exposures. The house key is handled by rekeying every lock it fits. The remote is handled at the garage door opener: its memory is erased so every old remote stops working, and new remotes are programmed. If the car had your address on its paperwork, do both before anything else. A locksmith can rekey the doors and, on many openers, clear the remotes during the same visit or show you the learn button on the motor unit.

The key and cylinder are doing their job; the bar behind the cylinder that drives the bolt, called the tailpiece or cam, has broken, slipped or twisted out of engagement. It is a small part. The locksmith retracts the bolt through the mechanism or removes the cylinder to reach it, then fits a tailpiece of the right length and profile. Your cylinder and keys are unchanged afterwards.
