on the 3 way pager press function 2 times then press unlock. that will get it out of valet mode

Sounds to me like the parking light output wire. They usually have a seperate fuse or the connection is bad. The connection on your vehicle should be behind the pass side kick panel and look for a wire to the white/purple wire and check that with a meter or light to see if it's kick out power. There is a possibility they used the negative trigger through a resister and that would be located behind the headlight switch. That will at least let you know and trace down the problem. Here is a link with that parking light info for yours. Hope this helps and let me know if you have more questions.

I had the same problem with my vs1100xr. The remotes for these (and other) unidens have a rolling code. Seems to me that either the remote runs out of new codes and cycles back to the beginning, or the alarm base unit somehow loses track of the codes. Either way, the alarm base unit stops accepting the codes of your remote, and so needs to be purged of its code tracking memory - reset, if you like. This is essentially the procedure for training the alarm base unit to recognise new remote (and forgetting old remotes).
This procedure is:-
1) Disarm alarm, or if in valet mode, take it out of valet mode (push valet button 3 times)
2) Turn the ignition on and off 2 times within 15 seconds.
3) Put the alarm into valet mode (push valet button 3 times) within 15 seconds of completing step 2. Alarm should beep, and remote training has started.
4) Within 15 seconds of completing step 3, push the button (#1) of the first remote you wish to use for the alarm. Alarm should beep, indicating acceptance of remote. Repeat for other remotes you wish to use - up to 4 in total. (Once the first remote has been accepted, you have all the time in the world to make the alarm learn other remotes)
5) Turn ignition on and off to end remote learning mode. Alarm should beep 2 times. New remotes have now been learned and previous remotes forgotten.

Some of these details may vary from country to country - who knows. If this doesn't work, I suggest that you contact Uniden in your country to obtain the procedure. Took me a few tries to get the timing right, what with the valet button hard to get at and having only 15 seconds between steps.

It could be set on car #2. Press function for 8 seconds and a light next to lock should come on. If the light next to unlock and lock (two lights) then it is set to #2 car (you can operate 2 cars with one remote). All you have to do is press function again to toggle between the two cars. You want to end up with only one light showing.
So, hold function for 8 seconds, then after a light shows, release and press function until you only see the one light.

Change the battery, 2-way remotes require 2 slim batteries on top of one another. Regular remotes only require 1.
