Hey guys,
I just recently stumbled across this site while googling something that I want to attempt to make.
I want to use my car's keyless transmitter to, in addition to the car, unlock my apartment door. I think I will be able to figure out everything but trying to create a proper receiving circuit for the car transmitter.
If I understand correctly the car keyless entry uses 40 bit encryption that changes after each use for both the transmitter and reciever. I am thinking that even if I am able to sync another reciever to the transmitter that it will effect the other receiver so that it won't work properly with the transmitter. Is that correct?
The main reason for wanting to use the car transmitter is less things to worry about on my key chain.
Any help, thoughts, ideas or suggestions would be appericated even if it involves calling me stupid for thinking something like this could work.
Thanks.
