Hi teejay, you are now in a wait period before you can reenter the code. Here's what the Volvo manual says regarding the incorrect code. Let me know how you make out.
If an incorrect code has been entered "rPt" or " EEEE" is displayed. Enter the correct code. After three unsuccessful coding attempts the set will lock and remain locked for two hours . "OFF" is displayed.After two hours have elapsed, re-enter the correct code.During the two hours waiting period:
Make sure the headlights are turned off to help prevent battery drain. Enter the code again once this time has elapsed.
