Car Alarm
My FOB no longer works for opening the door. Using the key it gives me about 20 seconds to get in and start the car before the alarm starts to go off. Is there a way to overide this? Is the FOB something that you can buy and program, neither of mine work anymore.

Just to clarify: have you changed the batteries in the fobs?

Battery is new. I'll have a look at the soldered connections, looks like micro surgery!

It is micro surgery. As long as you don't have a microscope, SMD soldering knowledge, ESD knowledge and a lot of soldering practice and the right tools i don't recommend DIY. Especially for the 4 th generation of the keys which use led free soldering and are ********************y as hell.
You can deactivate the alarm by turning the key in the drivers side door to the right first until the LED on the dashboard stops flashing. Than you can open the door by turning the key to the left.
Regards, Markus

Naw, they're easy to do with a steady hand, regular magnifying glass and soldering iron.
Just take your time.

I saw your repair, nice job. Glad both of mine work.

Yeah, easy as hell. How many did you repair successfully? And all versions of the circuit boards? And all kinds of wear?
Had some that were "repaired" by DIY guys. Conclusion: i reject now key fobs that formerly were repaired by DIY people.
Good luck!

I repaired my key fob by soldering in 3 new micro switches that I got from a guy in the UK. I have hands like hams and the eyesight of a mole but with the use of a head visor magnifier, fine tipped soldering iron and a steady hand I did it. That was 3 years ago and it still works fine.
I should probably do my spare key before I go completely blind.

I agree with you on that one. I am pretty good at repairing electronics and I know it's quite the job, and I have a soldering station that I use and am very handy with.

I don't keep track, exactly, but a rough estimate would be 150-200. Did you see my article about it in SlipStream?
I've also helped a couple dozen repair their own by guiding them to my DIY thread and providing advice along the way.

So in the long run better to have both of mine fixed or just buy 2 new head units and reprogram them.
mine works for 10 minutes with new battery, then buttons won't work, light still flash,
put in another new battery it works... tried everything.
