Does everyone find keyless a bit flaky?
I have it on my Polo GTI+ (and the wifes).
For both cars it'll only work as intended 2/3 if the time to open the car up. Sometimes it won't respond, sometimes you'll hear the click of the central locking system locking, even though it is already locked. It's not on any particular door either, it doesn't seem to matter whether it is drivers doir or front passengers door.
It's usually the first use after overnight parking, but not always.
