I bought my 2001 911 in Sept of 2017. It came with one key which would only start the car. The FOB did not work. I purchased a new fob and took both of them to the local dealer last spring and asked them to program both of them. They programmed the new one, but were not able to program the old one. The new one has worked fine till last week when it decided to quit. Any idea of what's going on? I think that I will visit the dealer in the next week or two.

Dead FOB battery.

 

The battery is new. I changed it out just in case.

 

Out of sync, install battery up-side-down, then remove and install correctly.

 

I tried that. It did not work.

Solder joint crack on the board in the fob....check to see if any joints looked cracked for the button.

 

I looked at it It seemed ok, but in reality I should have had a magnifying glass. However, the red light comes on, on the fob whenever either button is pushed. Does this confirm that the solder joints are good?

 

Been down this road many times. If it's not the battery, then it means a trip to the dealership for reprogramming. Always have a feyfob backup with these cars.

 

You can't reprogram a remote without the original key tag that comes with the remote when new, it has a 10 digit code that must be used.

 

That's why I don't throw away the bar code tag that is sold with the transmitter. I also make backup images of the code.

 

I stopped at the dealer today. He wants $169 for diagnostics. Then he will be able to tell me what the cost will be. I told him that I just want the key fob reprogrammed. "Sorry, we can't do that. Diagnostics first" Is he just screwing with me? Should I take it to my local Indy? By the way this FOB was new 1 1/2 yrs ago and was originally programmed by this dealer.

 

I was at a local dealer last week and their labor rate is now $215.00/hr. Ouch!

 

Buy an after market remote system from Bergvill for less than the cost of programming one key.

Befriend your local dealer and ask them to program you a key while getting a service done perhaps?

+996 on keeping a new keys swing tag/code.

There was someone on here claiming they could reprogram used keys without the tag, how much truth there was to that - i'm not sure...

 

I took my fob to a local computer store and for $50 they re-soldered all the connections and installed new button switches I bought on eBay for $10. Key fob works great now.
