56 Plate Touran

[solo2]

Not long has this car and one of the remote keys is playing up, will lock the car but not unlock it. Other key works fine.

Could it be as simple as the battery? I'm used to the remote locking slowly fading as the battery dies so not sure if this is the trait for it on these VW cars. I've been told not to take the key apart myself as I might lose the code on it (What code???) and getting dealer to do it will be a total PITA arse, so I want to be as close to certain that it is the battery before I subject myself to having to go there!

I've changed the battery before on the VW flip keys without losing any codes. I'd only foresee problems if you let the battery deplete to empty and then left it rather than replacing straight away.
