Hi all,

I have all three keys for my TS, but the second key fob doesn't work. It was like this when I purchased the car. I've changed the battery previously and the red LED doesn't light up on any key press. It all looks clean inside but something is obviously wrong. Anyone had the same symptoms before and if so what was the fix and how much did it cost?

Thanks!

Inside the key fob there is a contact that touches the battery may have been bent and not contacting the battery properly, If it is try bending it back up a little.
It may be a long shot but worth a try.

Thanks, I've had a bit of a go at that previously with no success - think I'll take another look though.

OK, I haven't taken it apart too far, but here's some shots. You'll have to excuse the dirt/dust! In the third shot on the connector at the back on the right you can see a small area that looks like corrosion, however I don't believe this is stopping contact. Let me know if the images are useful, thanks.

Hard to spot corrosion in a piccy...
Use a cotton bud with a trace of WD40 on it to clean the battery contacts.
Can you see in the picture where the battery contact also connects to the PCB (printed circuit board) via that gold flashed "print". Thats's another potential (:)) problem. You might be able to slip a piece of thin paper moistened with WD under it to clean it.

If non of this works, you are going to have to dismantle further to look for corrosion damage. Any white/green deposits around any of the electronic components spells trouble.

I agree, a further strip down will be required.
I have just stripped mine down to the circuit board and if you cant see any corosion you may want to look at getting a new key.
There is nothing that really could be wrong.

Thanks both. I've cleaned it as suggested but unfortunately still no joy. I took the buttons out from the top size so could also give a bit of a clean on that side. What's the recommendation for taking the key apart any further or any other thoughts?

Hi Eddie, thanks - I already have a new battery that I have tested in my working key and I also have the old battery from it which also has some power. Neither are working in it unfortunately.
