can anyone help me my e-class w211 model e320cdi car alarm does not work. have to open the car manually can anyone help me on how to fix this problem. i think it either a fuse gone or the battery needs replacing. however the car does start. and can someone tell me where exactly the fuse is for the alarm it self. damn thing does not have a card locating which fuse goes where. oh and the battery in the remote key has been changed.

 

hit the panic alarm button and seee if the alarm sounds and the lights flash. if the alarm does not sound youll need a panic alarm siren. common issue.

 

whats panic alarm sorry just got the car.

 

the red button at the top of the remote. hold it down for 3-5 seconds..the alarm should sound.

 

red button. theres only three buttons on the remote key, open,locks and open the boot. then there a light which flashes red when u press the open button and tht light blinks even tho new batteries been put in the remote key.

 

replaced a 7.5 fuse and now alarm works but the range is to short any advice. got the battery tested apparently its on 72% and needs charging. going to recharge it and see how it is or just get a new battery.

 

still playing up sometimes open otherwise have to manually open it. and the indicators automatically go on. but when you turn the engine on the indicators go off. i hve been told its most likely the reciever not sure tho.
