If your key fob is broken, the correct option is not buying a new one, but two. One should never accept a single key only.

If it starts your car OK when the alarm has been disarmed, then it could also be the remote key receiver at the car. Even that would be unlikely if it does not work via the RF port nor via the IR port (did you aim at the IR receiver at the door?).

Television would give good advice on fixing the key if it turns out to the issue (you can search for his previous posts on keys).

if battery is low, hold the key to your head and press button... it works... im not crazy!

first hold they key in front of a digital camera and see if you can see the infra red.

I forgot the picture

thanks for the replies, no it doesn't start the car when battery is disarmed and no the IR doesn't show when looking through a digi camara

 

[television]

Well you are going to have to buy one new one, if you care to post the old one to me, I will see if I can fix it for you

I can fix breakages, but not if the battery has been reversed, and I do not charge

 

[mitch1981]

is there a common fault on the circuit board, a bit of carbon was loose that was covering a component rectangle shape, could this mean any thing

 

[television]

What ever it was keep it safe

 

[mitch1981]

the coil is still on, its from the bit near the white plastic fastner and the top button if looking at your pic

 

[HughJarse]

You did try a new battery didn't you?

 

[television]

That should not be a problem then with luck, if the coil had come off the key would not start the car

 

[mitch1981]

yes tried new batteries

 

[television]

yes tried new batteries

It will not work with that piece off

 

[mitch1981]

it doesnt start the car or open/lock it, i'll just have to get a new one is 150 a fair price

 

[mitch1981]

it just looks like a cover for the component, ive held it on with the batteries connected too
