Remote key fault

One of my remote key fobs has stopped working. Other fob is fine, so I'm pretty sure it is the fob and not the receiver. I replaced the battery and initially it worked fine and the red led flashed as normal, but the next day it had stopped working. Tried another battery and same thing happened. Battery voltage has dropped to 2.6 volts, not sure if this is significant. I suspect that there is a drain due to a circuit fault.
Has anyone experience of any of the repair shops. I have come across 2 on the Internet. Autotronice is nearby, Remote Key Repairs seem to offer a comprehensive service. Does the fob need reprogramming after repair?

Try taking the battery out and putt it back in the wrong way around for a few seconds. Then put back correctly and it may work! It did for mine!!

The procedure for reversing the coin battery in the remote was covered in a Porsche technical bulletin. Doing this re-starts the processor on the circuit board.
 
Hope this helps. After battery and micro switch fault eliminated try this. I had a similar experience with 2of 986 booster keys. Ultimately traced the fault to dodgy solder connections on the integrated circuits underneath the battery holder. Under a 20x microscope I could move several of the pins with tweezers, the cause of the intermittent fault. As I already had micro soldering experience and equipment from a hobby repairing iPhones I repaired the IC chip pins on both keys and saved £410, Porsche dealer quite. Good luck.

nb this is my first post, hope it's ok?
