UPC question

[james78]

I've read in a few places that UPC apparently is coded to a car. I was doing some repair work on my car and had to remove my UPC but I also have 2 other second hand UPC from parts I bought of similar second hand cars. But problem is now I don't know which UPC is my original one that belongs to the car LOL. The all have the same part number and the same amount of fuse. I have access to CLIP, so is there a way to identify which one belongs to my car?

Hi,
I don't think so, try them one by one and you'll know then if it matters.
I think it'll be the alarm and locking if there is a difference.
When I once had one repaired on a Clio, the repairer asked for the key with the unit.
Good luck and please let us know the outcome.

ps next time you're in that sort of position mark the part you're removing.
