Ive lost my key fod 2 my 1993 honda prelude now the alarm keeps going off and the none factory fitted immobiliser wont let my car start! could you help me disconnect or disarm it??

You will probably need to replace the fob as that will contain the code to turn off the alarm and immobiliser. You might have to go to a dealership if it is a factory fitted security system.

why not just get another remote?? only around $50.00

You should be able to turn off the alarm by closing the driver's side door, insert the key and unlock the door. If this doesn't work, try the passenger's side door or trunk.

Yes, it's security chip that the factory installs in your key. You need to contact Honda

dealer only to rectify the factory immobilisor ,their is no way you can restart vehicle if this immobilisor is on ,try the spare keys and if that doesnt work then call tow truck and have it taken to a dealer but if this vehicle has additional alarm as well then this may need to be removed to reset immobilisor ,If the add on alarm is over two years old then after this time they go wrong causing no end of problems which is why i advise never to fit these remote start alarm thingys

Can I get a replacement Alarm key fob for my Rover 600 series , Factory fitted alarm, Thankyou

your nissan primera nats alarm is connected to the factory fitted stereo. check your stereo fuse as these are the symtoms i have done this before

The ST18x didn't come with a factory fitted alarm, so this is going to be more general.

Your alarm will have a manual disarm somewhere. If you have a small cylindrical device with your keyfob, there will be a receptacle somewhere near the drivers seat. You need to open the door and press the two items together. If not, you may have a button hidden somewhere around the place. In this case the procedure is usually to hold the button while you insert the ignition key and turn it to the ON position.

Some alarms have a small round key. If your alarm has one, or if your keys came with one and you didn't know what it was for, you can open the bonnet, pop a little cover on the alarm box (it will be bolted to the firewall, usually on the right hand side as you look at it) and turn it off until you can get it repaired, or get a new one fitted.

If none of this works and your alarm is an alarm only and not an immobiliser, you can simply open the bonnet and cut all the wires going into the alarm. If it is also an immobiliser, don't touch anything unless you're handy with a soldering iron and multimeter and have a few hours spare. (You would need to pull the cover down from under the steering wheel, then start taking electrical tape off the big block connector with thick wires, and then start rebuilding the wiring that's been chopped to make way for the immobiliser system on a colour-matching basis.)

I would take off the alarm and see if the problem goes away. If it does you know the problem is with the alarm. I am in the alarm business and will not have one on any of my vehicles unless they come that way from the factory.

unlock your car with the key, put the key in the ignition switch, remove one of the battery terminals now switch the ignition to the running position then put the battery terminal back on this will bypass the rovers immobiliser and alarm system
