Hi, I've just bought a 2001 ford focus estate, however I'm having an issue with the key fob. I picked up the car yesterday, and found that the remote control locking (rcl) was only working about 30cm from the car, which defeats the object. So I changed the battery and found that the rcl was now not working. With abit of research I found that you need to reprogramme the fob by placing the key into the ignition and going from o to II four times in six seconds, then hearing a beep press any button on the fob to get another beep. This has resolved the issue of the rcl not working as it's now fully functional, but the key now won't start the engine.
I have tried reprogramming the fob and directly turning the engine on, however the engine will turn over but won't start fully.
Also, the spare key works fine, no issues. But it's a non rcl key.
Any ideas of what I have done wrong, and how to resolve the issue?
Thanks in advance.
