I gather this has been asked before ,but I cant find any info .
So I have a BMW X5 that requires double neg pulse to unlock .The security system installed does not have any option for double pulse ,and there is no DEI distributor in this country so I cannot purchase the any of the dei products ,Im sure this can be done with relay(s) and a r/c network ..but how ? Some pone please help .....
