viper or valet 551u

remote start is on a 1999 ram was installed professionally. was working then stopped. now all it does is look the doors after a few seconds after you start the truck. is this a programming issue or is the unit toast. any help is appreciatedtimk

Thats not the correct model#. 

If it's still doing ignition locks I dont think it's fried.   Can you try reprogramming the remotes>   What is the "Date Code" stamped (little date wheels) into the back of the module?  Is the module square, with a little slide off door?  4 dipswitches underneath?

hi it has model 551U stamped on the top date code on back is 10/00 the slide door is half on the top and half on the side. it covers 3 pins that have a jumper to plug in to connect either side one to the center one.locks do not work by the remote but lock a few seconds after starting truck(locked keys in truck a few times this past winter). remote does nothing(light on it lights up)timk

Maybe it's me, but I dont ever remember a 551U.  So I looked thru my manual archive and lets say it's a 551R with a manual date of 08/99

Do you have a pushbutton switch plugged into the Blue programming port?  You'll need to turn the ignition on, press and release that button, then press and hold, then press button one on the remote, release, let go of the pushbutton, turn the ignition off and try button one for lock and unlock.

These systems would sometimes "Drop" remotes.  And would need them reprogrammed.

If this works we can program channels 2 and 3.

tried what you recommended nothing worked. finally took it in to Visions where it was installed to get them to look at it. installer tried reprogramming remote did not work he even tried a different remote did not work either. he told me unit is no goodtimk

Well that would be about the first unit that I saw die.

Are you sure the antenna is plugged in.

Did the LED on the module flash during programming?

551U is the Valet piece that is a universal remote start. It does not have remotes you need a master alarm to activate it. This is from memory and I am old.

If it was installed by the place you took it to and you were the original purchaser and you have receipt. Then this is a great time to take advantage of Vipers nationwide lifetime warranty. Please post back how much they charge you. It should be $0.00
