Remote control not working on Cobra burglar alarm.

I have a Cobra Globe 3900 model burglar alarm fitted to an Autotrail Cheyenne 840 motorhome. It's worked perfectly for three years. The other day, I opened the doors with the remote fob, loaded up for the holiday - but the remote control refused to lock the doors later. I assumed it was the age of the battery so changed it for a new one. However, the problem still persists, although I can still lock the doors with the ignition key. I've looked at the contacts on the doors and lockers - they all seem okay. Any ideas how to get the remote control working again please? Thanks!

SOURCE: Automatic door locks will not work.

you need to take it to the dealer and have them check the bcm for codes.... also have them check to be sure you have the latest software in the bcm.. its possible that you just need a software update... there are several TSB's covering the concern you have..... it can be a very simple fix with software or even a stuck lock switch may need to be replaced... without the proper diagnostic codes being read from the bcm all that can be done is guessing..and that can be expensive...

SOURCE: Jag S-Type -intermitent fault where the remote fob does not work

This does not sound like a fob fault - but a locking control module fault , either in the hardware or software of the unit. Get it checked at a Jaguar dealers. When unlocking using the key - as soon as the door is opened you should hear a chime sounding inside the car - this is a timer counting down to sounding the alarm. If you put your key in the ignition as soon as you open the door the alarm should not go off and the chime should stop. If it does not this again points to a fault in the locking controller.
hope this helps - good luck.

When i try to start me 2008 sonata the alarm goes off and the engine will not turn over. what can i do?


Your Sonata is equipped with a "Keyless Entry & Burglar Alarm" system. When the Burglar Alarm is activated, it KILLS the starting system through the used of a relay called the "Burglar Alarm Relay". This mode prevents engine starting with the key.
Solution #1
Disarm the system with the Keyless Remote (key fob) If you don't have this remote (or its battery is dead) replace the battery & try disarming again.
Solution #2
Enter the vehicle & insert the key in the ignition and turn the ignition switch to 'RUN'. Wait 3 to 5 minutes until the alarm stops. You should then be able to start the engine.

Have a qualified/certified Hyundai Service Technician properly diagnose this issue.

My 2002 Santa Fe is locked and the remote will not unlock. the remote has a new battery. How can I start the car.


First of all, has the burglar alarm been activated? If so, you can enter the vehicle with the key, put the key in the ignition and turn it to 'RUN' or 'ON" and then wait 3 to 5 minutes for the burglar alarm to stop. You should then be able to start the engine. You still need to have a qualified/certified Hyundai Service Technician properly diagnose the problem with the remote (Keyless Entry & Alarm System).

Power lock remote control is not working to open and close the doors while burglar alarm light (armed) keeps on flashing. When any door is opened, sound keeps "on" to indicate problem. The...


Check under the hood. Often, there is a small switch that needs to be closed when the hood is shut. This switch sometimes comes loose and when the hood is closed the button is never pushed. Find the magic button and reattach it to it's mount so that the hood will press it when the hood is closed and that should solve the problem. This button works with the alarm system.

Cobra alarm


After market alarms are horrible on MB's as they have built in alarms. If you mean the remote your going to have to get the frequency code from the manufacturer or have the dealership program it to control the alarm if the last 1 did.

If you dont know how the system works I would suggest removing it as most systems dont work well with the pneumatic central locking and fail by burning up wiring it is connected to.
