For sometime now one of the key fobs for the Freelander 2 has had problems opening and closing the vehicle. It was fairly hit and mis and the fob would only work within about 3m of the vehicle.
Did some searching around the net and found several articles on replacing the battery: –
Also this YouTube video: –
The battery arrived this morning so I popped on the soldering iron and followed the forum instructions and YouTube video.
I used desoldering braid to suck out the old solder from the circuit board. WARNING/DISCLAIMER: Use as little heat as possible. Too much could ruin the circuit board. If you doubt your ability to do this then get someone who has the correct skills to do it for you. GLR will not be responsible for ham fisted soldering failures!
Putting the fob back together was fine but it didn’t stay clipped together. To remedy this I used a small amount of superglue to hold the internal mating faces together.
The fob worked straight away. However I’m carrying both fobs at the moment until I’ve had trouble free operation for a few days.
In real life I'm a Software Engineer developing embedded software mainly in the automotive industry.
