Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Transmitter Resynchronization
If the functions on the remote keyless entry transmitter do not work, or, if only the remote alarm works, after the battery is replaced, then the transmitter needs to be resynchronized to the receiver. Do this by pressing and holding the LOCK and UNLOCK buttons on the transmitter at the same time for about eight seconds.
To verify that the transmitter has been resynchronized, the horn will sound and the exterior lamps will flash once.
