3rd Party Keyless Entry DIY (Why Not?)

[KevM]

So, on seeing this thread and with my key-fob recently expiring, I ordered a kit and fitted it last night.

Has anyone gotten to the bottom of the 15 second issue?

Same as a few of you guys, my kit works perfectly until the Security system arms and once the led starts the slow flash, the central locking deactivates. The kit is getting 12+volts all the time and the relays within the kit are still flashing the lights as normal, but no lock function.

Further to that, and before fitting the kit, the manual key in the door lock, will activate the central locking faultlessly, raising and lowering the windows as it should, until the Security arms. Once that happens, the central locking deactivates and the key only unlocks the drivers door. This triggers the countdown to get the key into the ignition. On doing that, I hear the locking actuators activate again and get a click in the drivers door.

Is this typical? Or is it likely that I have a faulty micro-switch within a door lock?

Looking at the wiring (number and colors) this one appears to be the same logic in a different form factor, but comes with a switch blade type keyfob. Got it all wired up and working thanks to this great thread. Now on to get the transponder chip and (insertable) key blade cut.

My kit came with 2 incompatible VW blades and they can be ordered from jom.de, but have something lying around that may work. Will see.
