keyless in 04 Ford Taurus problem

Installed keyless in 04 Ford Taurus and everything worked great.  Went to lunch and let the car sit for a while and when I tried to unlock it didn't work.  I unlocked it with the key and then everything seemed to work.  I tried it again and let the car sit for awhile (about 1 hour) and the same thing.  Is something going to sleep like the F-350? Please help!davedyer79

It sounds like the bcm is shuting down. You might try and pulse the door trigger wire through a relay off the unlock wire.

No, I am not pulsing the factory disarm, but I will sure as hell try that.  I thought something was going to sleep, but on all my tech notes it says nothing about waking up anything.  I will try both these suggestions and let you know.  Thanks for the quick replys guys.davedyer79

Actually the 04 Taurus do have the trim switch disable feature. I don't see any information listing it either, but they do have it. Try the other suggestions or wire up driver door priority if you want that will take care of it. Mike
