KCA KCA Keylock Cylinder Antenna 

KCA Keylock Cylinder Antenna

The Keylock Cylinder Antenna is designed to emit a RF
signal and identify the customer’s key in the ignition
system. This antenna is to be placed in the Ignition Switch
Lock Cylinder, inside the vehicle. Since it can be exposed
to the !nal customer, the antenna !nishing ful!ls the
highest quality requirements.
