Has anyone used a keyfob repair kit part number SACC3907 or have any information on using it?

It's a whole replacement circuit board inside the single button keyfob, with a replacement faceplate.

The button on my key takes a huge number of hard presses to work, it's a matter of time until it stops working entirely.

If I use this repair kit to replace the circuit board, does anyone know what needs to be done with the transponder chip in the key, can it be easily swapped across to work with the repair circuit board?


Alternatively, I've seen various subaru single button key fob repair services advertised online. Has anyone used any of them that they can recommend?

Thank you.

 

AFAIK the transponder chip remains in the key's back plate and is not affected.
The button and pcb operates the sigma alarm similar to how the separate fobs used to, and would need re-pairing to the alarm before use.
Usual problem with the key button is that the microswitch looses its internal fluid/grease and needs replacing. A relatively simple soldering procedure.

 

Thank you, yes that's the kit pictured.

Yes, it does occasionally work if you press the button hard and often enough, so most likely is just another microswitch.

It would seem then that my choices for repair are: use this kit, but have to re pair it to the alarm, or solder on another microswitch/get a local place to do that of which there appear to be quite a lot fairly inexpensively.

I think what I'll do is get some non-OE spare keys made first (as this is my only one), and then attempt a repair on this OE one with one of these methods as I would like an OE key.

Is there anything to keep in mind spec-wise for a replacement microswitch if I get one from an electronics supplier to resolder myself? I'd assume if it was just re-soldering the switch then no re pairing with the alarm etc. is needed?

Thank you Don.

 

Make sure you have a working PIN code for the alarm.
as for re-pairing the key to the alarm and changing the PIN there are many posts in the Security forum that have the various ways to do it.

A Uk member on Subaruforester.org repaired his using one of these (minimum order 10, I believe)

Still not got the second key then

Thank you.

I used the only OE key for a couple of years, and then unfortunately the car has sat for a couple more due to serious health issues.

I'm now well enough to give the car the TLC it deserves over this winter and get it back on the road for next year when the salt is gone.

 

In the end it needed a new microswitch soldering on, as thought.

I'm undergoing quite a big overhaul of the car this winter, but when I eventually get it back on the road I'll look at sorting out some spare keys as well.
