Thank you! Same thing happened with my A4. Opened the car with the working key. Kept that key away from the car. Took non-working key and put it into the small key compartment, switched on engine, left it for a few seconds, switched engine off, and the key worked from then.

Had the same problem with the fob not working after a battery replacement and your advice to start the car appears to have reprogrammed the fob. Thank you!

I just replaced the battery in my 2018, Q5, commonly People make the mistake of installing the battery backward, plz make sure the negative is up, After replacing the battery I pressed the Lock button and open button, repeat twice and my key fob started working without even taking it to the car.

Mine still says “change battery” even tho it locks

[@sachinpawar8518]

I feel the battery is not good , not sure where you purchased from. I heard from many people they bought new battery but it’s not fully charged or might have got drained out at the vendor/shop. Please try a new battery.

I change 5 new battery and still says "change battery "

[@sachinpawar8518]

@@7vuckovic I hope you brought the replacement battery from a genuine vendor. If yes then please take it to expert mechanic or the dealership to see if the issue is with battery or the fob itself. My steps are for self resolution and mine went away as shown in my video. Incase, if I had same issue like you then I would have taken the dealer.

Fab? I'll try it shortly...see if I get stuck in the cold

[@Homebased_Official]

Mine won’t work - don’t have a second key to get into the car

[@sachinpawar8518]

Try using the emergency key to get into the car and keep the key fob into the slot I showed and try starting the ignition and then start the engine. I didn’t tested this but you can try to see if that works.
