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.
Circuit Description
The keyless entry antenna - right is located in the right hand B-pillar area and is used as a short range low frequency (LF) transmitter. As a vehicle with locked doors is approached with a key fob and the exterior door handle switch is pressed, the keyless entry antenna transmitter broadcasts a challenge to the key fob in approximately a 1 meter range. If the response from the key fob via radio frequency (RF) is valid, then the locked door will be passively unlocked/unlatched and allow the door to be opened.
