Hello,
I installed a 552t in a 98 expedition for a customer. Everything worked fine until it gets very cold. The problem seems to be the 555F does not work properly when it's very cold out. Of course this is the most important time for it to work. Has anybody heard of this or know any way to remedy it?
Thanks
Shaun

hi a cold temp the pellet in the key freezes the way it was explained to me is the pellet in the key vibrates when the pats ring energizes and transmits frequency when things get cold they stiffen up and can't vibvrate anymore hope this helps ------------- good luck

The 555f is hot glued right on the cylinder. It has always worked perfectly. I have had problems with this guy before. He tries to blame everything that goes wrong with the truck on me. I haven't actually seen that it doesn't work, but I was just checking to see if this was a common problem. He said that after either the temperature outside or the truck warms up it works fine, only a problem when it's cold. He also said that the theft light comes on when it doesn't work so it does seem like its a problem with the 555f.

the pelet gets cold and cannot transmit the code well. This happens to most transponders. There is not much you can do but one one thing is by using a 555u with a spare key inside (if u have one to give up) or you can always program a new key to the car i can show u how!!

make sure you are setup on tach monitor and not voltage. cold is bad for voltage. and you could try a 555u i suppose, just get a spare key thats coded and verify that by starting the vehicle with it. then mount the ring and hide the 555u box.
