The batteries in both my car's keys have gone. Unfortunately I haven't changed them as soon as I've noticed they are about to go and now, even with new batteries, the remotes on both of them are not working. The LED on the keys are lighting red. I've tried all the procedures to recode them I found without result. I've tried - this one: how to program a vw, seat, audi coded key, when new battery fitted, or recoding new key. - YouTube - this one: http://www.audi-sport.net/vb/a3-s3-...programme-your-audi-key-fob-instructions.html - this one: How To Program Reprogram Your Audi Remote Key Fob - A4 | eBay - and both these ones: Ross-Tech: VAG-COM: Remote Control Matching Info The Ross Tech mentions at some point that in Central Convenience - Measuring Blocks - group 003 or 007 I should find a field that will show how many remotes are stored. There is nothing like this in any group. How do I match the remotes again? Does the red LED flashing on the keys when I press a button means something? Does it also light in green in some cases?
