This is a new one for me. 2018 DB11 V12.

Was at lunch, came out and the FOB opened the trunk (boot) then unlocked the doors, but when the start button was pushed I received a "no key detected" message. Sitting there in the car trying just about everything I could think of, suddenly the sync occurred and I was able to start the car and get it back safely home and in my garage.

After numerous attempts of changing the 2032 FOB battery and disconnecting/reconnecting the car battery (which is/was up to voltage and now on a CTEK), the car started one time, and the door/trunk lock/unlock worked. Now, there is no communication between the fob and car at all.

I only have one FOB for this car. It does not appear the system immobilizer is/was impacted, just doesn't recognize the key all of a sudden. I'm looking for any input from anyone who might have experienced similar or same and anything you can offer to look at.

Since this I've contacted the closest AM dealer (in Tampa) and ordered a new complete FOB and metal key set (two FOBS and a metal emergency key). They are preparing this set now which takes weeks, then they want the car in their shop to program keys. My concern now is I cannot get the car started when the appointment comes up in January.

Any input appreciated.

I don't have clues on why this is happening, but at least on the Vantage, you can always start the car via a "traditional" ignition slot in the armrest storage between the seats, could be interesting to see if that is working for you as well:



If so, you just need the metal emergency key you ordered from the dealer to open the doors and you might be using the car sort of normally until January?

Thanks for the reply! Appreciate it.

Yes, I know about the emergency start by inserting the key fob end into the traditional like ignition slot in the center console. I should have mentioned this in my first post, but that does not work either. It's as if the entire fob is for a different car. At least not mine anymore.

I cannot say this has ever happened on any other car. I posted up here wondering if this has happened to anyone else and how they resolved it. My fear is this is a rare failure.
