Hi I am in the UK
I have a R129 SL

Just changed the car battery and now my flashers are on constantly - though no audible alarm.
My key should be the infra red remote type but its never worked and isnt as simple as changing the battery on the key.

It looks like my problem is that as i havent used the key to lock or unlock the car and only use it manually; then the alarm is going off. Its been flashing now for the past hour so I dont think its going to stop - even when driving.

Any ideas on how to reset the alarm?

Thanks

Alarming

alone, try reading your owner's manual. I believe the alarm is armed and dis-armed by manually inserting the key and turning it twice. Also please fill out your profile. The UK is pretty big, and the R129 came in many flavors through the years. We can assist you better if we know more about you. You might have MB tech or more informed forum member living nearby..................Thor

thanks. My local dealer has now managed to disarm it by disconnecting something - my wife had to sort it out so not quite sure yet how!
