My daughter has been having a "No Key" error with her 2015 Accord EX since getting it back from the body shop where she took it after a pretty good wreck.

The car is supposed to unlock the driver's door when the key FOB is brought within 18", but instead nothing happens and she has to unlock the door manually. Then when she gets inside, the orange "no key" indicator on the dashboard is illuminated, and a text display at the bottom of the dash shows "No key". The car starts and runs fine (and looks beautiful!) but she misses the keyless entry and startup.

She says she replaced the battery in the FOB less than a year ago and it was working fine before the wreck.

Can anybody suggest where best to begin troubleshooting this problem?

Thanks!
