A daytime thaw sends meltwater into the keyway, and overnight it freezes with the plug held solid. The key goes in, meets resistance, and the natural reaction is to turn harder. Brass gives before ice does, especially at a deep cut that has thinned over years. Cold also stiffens old grease in the cylinder. De-icer, gentle warmth and a dry lubricant break the pattern.

The tailpiece is the flat bar that sticks out of the back of a deadbolt cylinder and turns the bolt mechanism when the key turns; on a knob or lever set the equivalent part is a cam or spindle. It carries all the twisting effort, so a bent, worn or broken one is the reason a key can turn without anything happening. It is a small part to replace, it comes in several lengths, and the right length matters.

It is worth having. The door between an attached garage and the living space is in practice often the softest way in, since a garage door left open leaves a passage knob as the only barrier. A thumb-turn deadbolt there costs a few minutes a day and closes that gap.

The locksmith checks your authority to request the work, examines the door and lock, and tells you what it needs. The knobs, plates and cylinder come off, the case slides out of the door edge and is opened on a bench, cleaned, re-sprung and repaired. Keys are made or the cylinder rekeyed, the door pocket is tidied, everything goes back on, and the strike is adjusted. You test the finished lock from both sides.

Yes. An exit alarm module sounds when the device is used, which tells staff a door meant to stay closed has been opened, but it does not add any resistance to the push that releases the latch. The alarm is a notification layer on top of hardware that still opens under one motion, which is why it suits stockroom, dock or perimeter doors where entry through that opening should be rare.

It is the emergency key. When the fob's battery is flat, or the car's own battery has died and the doors ignore the buttons, the blade unlocks the driver's door mechanically. A small release on the fob lets it slide out. On a replacement fob the locksmith cuts this blade to your door lock and shows you where the keyhole is, since on some cars it hides under a cap on the handle.

Often, yes, provided its hardware and chip match what your specific vehicle accepts, checked against the vehicle's identifying information before anything is ordered. A used OEM smart key is also checked for prior registration, since some become permanently unusable once reset or removed from another vehicle, so confirming eligibility first avoids buying a fob that never registers successfully.

It varies by make and model; some systems hold only a handful of identities, while others allow considerably more. Many vehicles let one working key on hand authorize adding another, though some ask for two working keys and others use a different programming route entirely, which is why all-keys-lost situations are handled differently from adding a spare or a second driver's key.

Meltwater from a thaw can run into the keyway during the day and refreeze overnight, and road salt and brine thickens grease inside an older cylinder. Both make the key resist turning or stop partway, and both respond well to gentle warming or a lock de-icer rather than force.
