300SL Door Locks & Keyless NOT FUNCTIONING

[STEANSON]

HELP! Last night, as I attempted to roll up my windows with the keyless remote (by locking the doors) I noticed the red blinking lights KEPT blinking...no windows rolled up...Well, today, upon arriving at work I tried locking the doors and I got NO response at all...after tinkering I settled with manually locking at the trunk...but then when I tried to unlock I get nothing....not even the blinking indicators on the car. AND I have that common problem of the key itself not working in the locks. Should I call a locksmith??? I am stranded and can't get in the car! (Please edit this as you see fit) Oh, my remote "works"....I get the red LED indicating it is working. Thanks for any advice.
