The sensor is actually in the rear screen glass....Gazellio said:You can easily find the self programming method by search this forum it take about 10 seconds and is easy to do.
1) Get in and close all doors. Turn ignition on and off quickly and remove the key (all within about 5 seconds).
2) Within 30 seconds of turning the ignition off, while holding down the "unlock" button, press the "lock" button three times. Release the "unlock" button. (You may or may not get the confirmation from the door locks.) Holding the key at your head level provides best results as the key sensor is in the side window pillar.
3) Repeat for each key you want to initialize within 30 seconds after the last one you initialized (if you have more).
4) Right after doing the last key, quickly put the key back in the ignition and turn it on/off again to finalize.
What message?motosport3 said:I'm still getting this msg after switching to a new battery? Is reprogramming necessary? All the functionality is fine, its just the msg on the dash lights up after starting up. This happens on another key we have which is new now as well.
I recently had my BCU replaced. Is that related?
Have you tried reprogramming the keys together as set out above? If its a new Key it MUST be programmed at the same time as the existing.motosport3 said:"Key Battery Low" is the message I'm getting on the key where I replaced the battery and also for a brand new key we got from the dealership.
