My name is ***** ***** I would be happy to help. Reminder, I have not been paid at this point and won't be until I receive a positive rating from you. At that point I will receive a portion of what you've already paid Just Answer.
I'd like you to perform the cable reset procedure. This typically restores faulty electronic components on the vehicle when this sort of thing happens. It has solved many issues over the years. Here it is:
1). Disconnect both battery cables from the battery (positive first then negative).
2). Connect both cables together with a jumper wire of some sort. DO NOT connect the battery posts together, only the cables.
3). Turn the ignition switch to the ON position and leave it for 10 minutes.
4). Once that time has passed turn the ignition switch back off, and then reconnect both cables (positive first and then negative).
5). Turn the ignition switch ON and see if you can enter the code.
If that doesn't work let me know.
You can go ahead and rate me positively. Don't worry, there won't be additional charges for posting questions to this thread after you rate so we can keep chatting. Thanks
