The car came with a second key that grinds and catches in the rear door, unlike the smooth key you use every day on the front two. It eventually turns, but the roughness has been there since the day you brought the car home.
Some vehicle lock faults are entirely mechanical, a cylinder worn from years of use, a linkage rod that slipped off its clip, while others sit in the electrical side: a tired actuator motor, a corroded connector, or a coin battery inside the key fob that has finally run flat. A locksmith working on a modern vehicle checks both sides before deciding what to repair, since a stiff key points first to the key, the cylinder and the mechanical path, while trouble that shows up only with the switch or remote points the other way, and the two call for different parts entirely.

Scene 1
A working door, right next to the one giving trouble, is one of the most useful things on the whole vehicle during this check. The locksmith tests the good lock first to see how the cylinder, the latch and the remote are supposed to feel and sound, then repeats the same actions on the affected one. Differences that show up in that comparison, a looser turn, a missing click, a delay before the actuator responds, narrow where to look, and checks of lock position, fit, cables, connectors, wiring and actuator operation follow before the failing part is named.
Scene 2
When one door lags behind or ignores the fob while the rest of the set responds together, the repair focuses on that single point, the actuator, its wiring or its connection to the vehicle's locking module, rather than disturbing doors that already work. Once the failed link is repaired, the locksmith cycles the fob repeatedly and watches every door, confirming the whole set locks and unlocks as one action again.
Scene 3
A repaired lock is a good moment to think about backup. A spare key kept somewhere other than inside the vehicle, or a second fob programmed for another driver in the household, means a future battery failure or a lost primary key is an inconvenience rather than a repeat of today's visit. The locksmith can cut or pair that spare while the vehicle's details are already on hand.

It is worth addressing, since a cracked case lets in moisture and dust that can reach the circuit board and buttons inside, shortening the fob's working life. A replacement shell or a full replacement fob, paired to the vehicle, resolves this alongside any battery or pairing issue.
Yes, generally by cutting to the vehicle's factory code or by reading the existing lock cylinder directly. Where the vehicle needs a transponder chip in the key for the engine to start, that chip is fitted and programmed as part of the same visit.
A key that spins without effect points to the connection behind the cylinder rather than the cylinder itself: the linkage rod that carries the turning motion to the latch has likely slipped off its clip or broken. Reconnecting or replacing that rod typically restores normal operation.
