How to Replace Key Microswitch

Firstly you will need a fine point soldering iron, some fluxed solder, the correct microswitch and a steady hand/clamping holder.(The final pic shows the size of 'tip' required compared to a 1p!)


Separate the key fob by opening it via the slot at the top of the key fob near the metal part of the key.


Then you need to remove the PCB (printed circuit board) from the fob. It is just a press fit into the plastic case but be careful not to snap the pcb or damage any of the components on the reverse side.


You can see where the switch fits as there are 2 location holes that align the switch and the 4 contact points to the pcb where the solder needs to be. At this point I put a tiny spot of solder on each of the four contact points. (You could just solder on top of the switch if you like but I believe this gives a better contact)


Place the switch into the required position and hold in place with a small croc clip. Apply heat to each of the 4 contact points until solder melts. And hey presto one re-attached switch.


Just gently press the pcb back into position in the fob, close the fob (checking battery and outer 'button' position). If all this goes swimmingly then you will have one fully functioning remote key fob again! A saving of 175. Not a bad job!


If you don't have a soldering iron or the patience to do this I am willing to do it for you for 15 plus p&p (will have to look into how much p&p would be) There is a chap in Slovinia who offers this service on ebay at 20 + 7 p&p.
