Yes, It sounds about the same as happened to us with our 145. Left the interior light on one night. Next morning off to the 'local' dealers 30 miles away on a truck after I'd replaced the battery myself. Took them all of five minutes to reprogramme the b****y keys and prepare thier bill. I was vexed, could have saved the whole recovery effort if they'd been prepared to tell me the procedure over the phone. If I remember right it is helpfully . Hopefully you have the master key. See other posts for more details, it's all here. Helpfully it's notcovered in the owners 'instruction book'
