Hi assume you have reset the battery disconnect circuit (tripped by button in boot next to charge socket). Instructions should be in your owners manual. You will also have to re-reference the seats.

OK, my Aston is a db9 but the battery disconnect button is under the right rear seat squab. I just pull it up from the Velcro that holds it... The gearbox release controls (for towing) are under the left rear seat squab. This probably doesn't help but I thought I'd mention it!

Suggest you press the battery disconnect button in boot next to the charge socket. Then disconnect battery for 2-3 mins. Reconnect battery then press the battery reconnect switch under seat. This should re set all the computers and then try.

flyboy1: +1 I agree but be advised that you may also then need to reset certain others items such as the windows, seats and possibly even let the engine "relearn" misfire corrections.

Cheers, Mark

Had the same issue on a 2002 DB7. Replaced battery, made sure the battery switch was in position and not depressed. Then unknown to me found out there is a "RESET" button on the rear wall in the trunk "boot" that needs to be depressed. Also need to rest alarm system and then all was well.
