Questions about this item

What does the 433MHz frequency mean once the fob is in daily use?

The fob communicates with the vehicle on the 433MHz band, so lock, unlock, panic and trunk commands travel over that frequency.

What standard or interface does the 4A chip use, and what does it cap in practice?

The 4A chip works with the Jeep Compass 2017–2020 immobiliser system; the remote will only function after a locksmith or dealer programs it to the car.

What does the fob physically need to fit or mount on the vehicle?

The fob measures 7.3 by 3.7 cm and includes a metal door key blade that must be cut to match the vehicle’s lock cylinder.
