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.
Which lock is affected shapes the whole visit. A door that will not respond to the key usually points to the cylinder or the linkage rod behind it, a trunk or hatch that spins without opening points to a worn or disconnected cam, and a door that ignores the remote but still answers the key points to the power actuator rather than the lock itself. Reading the symptom correctly narrows where to look before the panel comes off, and checks of lock position, fit, cable routing, connectors and the harness follow before the repair settles on the part that failed, rather than replacing hardware that was never the issue.

Scene 1
Weatherstripping around the affected opening gets a look before the panel goes back on, because a perished or torn seal is often how moisture reached the parts that just failed. The locksmith also checks how the door or hatch sits in its frame, since a panel that has sagged slightly can put pressure on the latch and mimic a lock problem that is really a fit problem.
Scene 2
A fob that has gone quiet gets a fresh coin-cell battery first, matched to the size the manufacturer specifies, and the buttons and case are checked for cracks that could be letting in moisture. If the vehicle no longer recognizes the fob's signal at all, the locksmith re-pairs it using the vehicle's own procedure, or supplies and pairs a replacement fob where the original cannot be recovered.
Scene 3
A lock that has just been serviced benefits from a dry start. Worn weatherstripping near the repaired point is worth attending to soon, since it is the most common way moisture reaches a cylinder, a linkage or an actuator a second time. Wiping down the door sill and keeping the seal clean through the wetter months goes a long way toward keeping today's repair from repeating itself.
What shapes the quoteEnnisclare Park Locksmith Specialists
FeesSame any hour
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.
Note which lock is affected, whether the key turns without effect or resists turning, and whether the remote behaves differently from the mechanical key on that same door. That description helps the locksmith bring the right parts for the specific fault.
Yes, this happens fairly often because a trunk or hatch lock gets used far less than the door locks and can seize from disuse, dust or corrosion, or spin freely if its own linkage has come loose over time.
