what frequency does the car transponder challenge the key and what frequency does the key respond at?
is it a rolling code challenge like unlock/lock?
- galangalalgol 7y agoRolling yes, all on same freq. 315 mostly. Some 433

- galangalalgol 7y agoAlso some new ones use ultra wide band. A super short pulse that can tell how far the fob is based on how long it took to respond to the challenge.
