The red dot are the old keys, it was MB's way in the 80's of showing off the car had an alarm. The new ones don't have it.

Your lock is probably stuck, since hardly anyone ever uses that feature. Try some graphite powder in the lock.

Thanks, I will try that. I hate forcing things.

FWIW, my locksmith says not to use graphite. Use WD40.

Liquid's will attract dirt.

my brother, a locksmith uses the saying "graphite is a locksmiths best friend" meaning it generates lots of business.
I learned that the hard way when I squirted Graphite in a new SAAB and a year later the lock jammed up. It gets into the pins and dries out and they stick.
I suggest WD40 or better yet, Tri-Flow spray on locks.
