Transmitter Key

An infrared transmitter with transmitter window, a push-button for operation, a battery compartment with 4 batteries and a foldable 4-way key are accommodated in key head. The key is folded out by means of a push-button. If a transmitter key is lost, it can be ordered in usual way by specifying locking mechanism number. Up to 8 transmitters can be adapted to a locking mechanism by manufacturer.

If locking mechanism on a vehicle is replaced, transmitter and infrared remote control module also have to be replaced. When transmitter button (b) is operated continuously, transmitter switches off after about 30 seconds to avoid discharging batteries. As of 10/93 size of transmitter key was reduced by approximately 40%. For this reason mechanical key shaft on transmitter keys up to 9/93 are not interchangeable with those in transmitter keys as of 10/93.
