I recently experienced a completely flat battery after not using the car for 2 weeks. The car jump started instantly and was driven for around 20 miles to charge up the battery. All was fine. I then did a 400 mile round trip to Stafford to collect and fit a recently purchased hard top. Again all fine. Another trip of some 20 miles, all fine. Then when I went to use the car the central locking failed to operate. I opened the car with the key, and tried to start it, with the result that it turns over fine, but will not start. I have tried using the key with the immobiliser silence button on the steering column to reset things, but to no avail. I also tried disconnecting the battery on the positive side to see if that would reset any of the electronics, again no result. If anyone has any answers, I would be very grateful, or for any guidance.
