Car locks / keys?
Posted: Fri Mar 17, 2023 9:45 am
Anyone happen to have investigated receiving car key (remote lock open/close) codes with the duo?
Some time ago, I noticed that my car key happened to output a signal which changed the state of a remote control socket. From googling, frequency seems to be the same.
I'm thinking of something like turning house outdoor lights on/off with the car keys if necessary when leaving / arriving at the house. (As a more specific case, for me particularly, could also be useful for debugging whether my car remote lock issue is with the car or they key).
Sending the codes (if even possible, not sure how the resync works) with a Tellstick might be a bit of a security risk - if one can record codes & replay them (and resync the car & key for a fresh start so the recorded keys will work), it would in principle make it possible for someone else also to record &replay the codes.
