Got a new key fob for the aftermarket alarm on my X, works perfect and I've used it for 2 weeks now. Went out to start it this morning and the red THEFT stayed at a fast flash telling me it wasn't going to start. I had it towed to the dealer cause all 3 keys appeared to have dropped the code. At the dealer once off the flatbed I thought just for giggles and wouldn't you know it all 3 keys worked. Any thoughts/ideas. I'm leaning towards the after market alarm interfearing with the stock system. I was going to have a remote start hooked up the the alarm, but now I don't know.
