My questions never fit the available categories. This is the best I can do. Otherwise I have to shove it all in off-topic.
My car is a 2003 Diamante. It works well for me and I am happy with it. But I have a problem with the remote unlocker.
I have two of them. One is completely broken. The other is on the way out. The problem with both is a micro-switch on the circuit board that operates the unlocking mechanism when pressed. The remotes each contain three identical micro-switches for different operations. The switches have five tabs, soldered on the surface of the circuit board. On both remotes, the switch that operates the unlocking mechanism is faulty. On one it has frozen completely. On the other it is very sticky and barely makes contact when pressed very hard. Often it doesn't work at all.
I see three (financially reasonable) ways of fixing this:
1. Get a remote from a dismantler or someone else and reprogram it to my car. I have no idea how to do this or what is involved.
2. Replace the faulty switch with a good one from the extra remote.
3. Buy a third-party remote and replace the existing one.
If (1) could be easily done that would be best. Otherwise my preferred solution would be (2) but I need help for this. I am not up to soldering work on tiny circuits. From past experience I know that if I try I will destroy the remote. I need someone who does this professionally or as a hobby with the right equipment and skill. It is not difficult for someone who knows what they are doing. One good switch needs to be unsoldered from the broken remote, and then used to replace the failing switch on the working remote. I am prepared to pay someone a few dollars to do this.
Alternatively, if anyone knows what is involved in getting another remote to work with my car I would be interested in that. Advance thanks to anyone who can help with this.
