DenishP4 Posted August 26 Share Posted August 26 Just moments before this occurred, the vehicle was functioning properly. I got in the car and tried to turn the diamond key in the ignition, but it remained stuck, as if the steering lock were engaged. After giving the wheel a little tug, I finally got it to position 2, but I still couldn't see anything on the center display or in the cluster lights. I turned the key to start (with my foot still on the brake since it is an automatic), but it did not work. I left the battery negative for a few hours, and now whenever I try to start the car after reconnecting it, the center display shows a key with a vertical line through it. After re-connecting the battery and trying to start the engine using the key, I only get this indicator once; further attempts do not display it. The meaning of this sign is "Key Not Recognised," according to internet searches. Is it necessary to consider obtaining a replacement key because the car's CAS 2 system detected the key in the ignition but did not receive the valid code? On the other hand, is the absence of dashboard cluster lights a more serious issue? It was not a key recognition problem, according to one key replacement shop. Headlights, wipers, radio, fan controls, driver-operated window switches, and engine control are all absent. The internal central locking switches and hazard warning systems are operational. Visual checks were all fused. Battery connections in the engine compartment and the boot are 12 volts. There is a 3v diamond key battery. The driver's door cylinder key lock is used to lock and unlock the doors. As the driver locks and unlocks the door, all windows are down or up. I would much appreciate any recommendation. Please put me in touch with a local in the SE4 2JH area of London who can come get me started; I'm willing to pay for the service. Quote Link to comment Share on other sites More sharing options...
CelestialSeeker Posted August 26 Share Posted August 26 Sorry, I'm not very knowledgeable about electronics; but, I may give the battery disconnect method another go; however, the car goes to sleep after 20 minutes. It was merely an idea. It is also necessary to scan for fault codes. Quote Link to comment Share on other sites More sharing options...
DenishP4 Posted August 26 Author Share Posted August 26 Hello, my scan tool is a very basic Launch 129, and it has not detected any problems. The inpa software on my laptop isn't working properly when linked to the car. Neither the battery nor the ignition symbols turn black to indicate that the two devices are connected, and I keep getting problems no matter what I do. In my opinion, turning on the ignition (the cluster lights) is necessary for it to function properly. Quote Link to comment Share on other sites More sharing options...
