E53 4.4 won't turn over

[ibkevman]

Hi all. I recently parked my X5 on a surface lot at my work this past Friday morning and returned to it late Monday evening after being on vacation to find it won't start. The battery seems to have plenty of juice as everything else appears fine and the lights are bright as ever. When I attempt to start her up, I get no noise at all. She won't even pretend to turn over.

Seems weird that the starter would decide to go out at that very point. I tried locking and unlocking the door from the outside hoping it may have been cause by the alarm being set off. I'm also going to try my spare key later this morning.

Any ideas as to what could have caused this? I did a search for various search terms and couldn't find anything. Any help would be appreciated!
