Fault symptoms

The car does not start. The message “KEY NOT ACCEPTED” appears on SID.

Conditions

A key not programmed for this TWICE module is used or the transponder key is missing or is faulty.

Diagnostic help

”KEY NOT ACCEPTED” is shown on SID. Try using another key which is programmed for this TWICE module.

Main condition

The diagnostic trouble code is generated if a fault is found during two test cycles in succession. A test cycle lasts one second, i.e. it takes two seconds from when the fault occurs until a diagnostic trouble code is generated. If the fault disappears, the trouble code is deleted from the control module memory after the ignition has been turned on 20 times.

Diagnostic trouble codes are not generated if the voltage is below 11 V or over 14 V.

Check wiring harness.

Jiggle the wiring harness at several points and in different directions to reveal intermittent breaks and short-circuits in the leads. Observe the multimeter, test lamp or diagnostic instrument during the test.
