Hi,

Twice today when I unlocked the car and put the key into the ignition and turned nothing happened. Lights didn't come on and engine did not start. I got out of the car and re-entered and put the key in and turned and the ignition lit up and engine started no problem. Same thing happened this evening too. But took a few attempts to re-enter the key and it started up. Could a low battery in the key be a reason for this or is it more serious?

Thanks

Your car sometimes fails to wake up to start as evidenced by no-light on dashboard.

Once you have the ignition key inserted in the "Ignition switch" the FOB battery is no longer involved. Key is read directly through contactless coils.

-- Note: a bad FOB CR2035 battery cell is usually signaled on the dashboard of these cars. Not here, correct?


-- Go ahead and use a SCANNER to retrieve available faults.


-- Take sometime to say hello to your BATTERIES...measure voltages!
​​​​​What sort of AUX does your car packs:
a good "SLA battery" or "Farad-caps. module" ?


-- After these basics I'd concider a quick/simple car REBOOT to note any direct improvements of the EIS + KeyG solderless modules working with F-SAM power Mgt module.


-- Does your car features "Blind Spot" bumper radar modules... have these being working reliably with mirrors or part time amazing??
