2003 SL500 secrity system malfunction
I have a 2003 SL500 with about 40,000 miles on it. For no apparent reason the alarm system will go off, lights begin to blink and, recently the doors began locking at the same time. This last time I had to use the key to open the doors (the f.o.b. wouldn't work). I start the car and the SOS warning is on the data screen telling me to get the car in for service. Any ideas?
