Replacement Car Keys in Eastleigh

A replacement car key has to do two things: physically operate the locks, and satisfy the vehicle's security system. Getting both right is what separates a working key from an expensive keyring. Keys are supplied, cut and programmed on site in Eastleigh, so the car does not need moving.

Types of replacement key

Remote keys

The familiar key with buttons for lock, unlock and boot. The blade is cut to the vehicle's lock code and the remote is paired to the receiver so central locking works as it did before.

Transponder keys

Almost every car built since the late 1990s carries a transponder chip. The immobiliser interrogates that chip each time the ignition is switched on; if the answer is wrong the engine will not run, even though the key turns. A replacement transponder key is programmed to the vehicle so the immobiliser accepts it.

Smart and proximity keys

Keyless vehicles detect the fob rather than reading a blade. Replacement smart keys are programmed for keyless entry and push-button start on supported models, and the emergency blade concealed in the fob is cut so the door can still be opened manually.

Key cutting

Blades are cut to the lock code for the vehicle rather than copied from a worn original, which means a new key often turns more smoothly than the key it replaces.

Programming

Programming introduces the new key to the vehicle through the manufacturer's own routines. Where the vehicle supports it, keys that are no longer in your possession can be removed from the system at the same time. See car key programming for more detail.

All keys lost

When there is no working key to copy, the key has to be created from the vehicle itself. That normally means reading data through the diagnostic system or the lock, cutting a blade to the correct code and programming the new key from scratch. It takes longer than a spare and costs more, but on most vehicles it avoids recovery to a dealer. If this is your situation, read lost car keys in Eastleigh.
