Rover 75 remote key not working
Hi.
A couple weeks one of my remote keys stopped working (locked the car with the remote at night, next morning didn't unlock using the remote, no response from the car, had to unlock it with the key on driver's door). The battery for the remote was only 6 months old but I've changed it anyways, still no luck. There are no red LED on the remote, so I've assumed that something was wrong with the key and went for the second one. The second remote was ok but stopped working after a week, same way (went to the store, remote locked the car and when Ive returned, I'm not sure if I pressed the lock button again because the turn signals flashed but then no response and the car remained locked) The second remote was showing no red LED, went home to replace the remote battery, but the LED was now solid red by itself (not flashing, just on).
In a nutshell, everything works fine except remote lock and unlock. Since finding someone with a T4 here in Portugal is at least challenging, is there anything that I should try? Thanks in Advance. |

Give this a try: https://the75andztclub.co.uk/forum/s...d.php?t=305142. If you haven't already got it, download Toaf, lots of info in the search.

Well, disconnecting the battery leads and touching each other has not solved the issue. It's still the same as before.
Any more suggestions? |

When you've done this come back for instructions on how to re-code your remote boards. I've added secondhand remote boards to two cars using Toaf, quite easy following MarinaBrian's instructions although I think it was a guy called Trevor who originally discovered the possibility. Regards |

Hi Vitesse.
I've managed to borrow from a friend of mine a VW KKL OBD2 cable. I'm going to figure out how to short pins 7 and 8 without being irreversible or damaging something. I've already dowloaded every file from TOAF, including version 43. I'm going to see If I'm successfull this weekend and will give you guys some feedback. Also, since TOAF is pretty much new to me, any guidelines would be appreciated. Best Regards. |

Here's a link to the instructions to add remote boards: https://the75andztclub.co.uk/forum/s...d.php?t=271435 post 2. You'll need to open the keyfobs and find the sticker with the code on the remote boards. No creating bar codes like I believe the T4 has to do, my own T4 is a useless gigantic paperweight. Finally, and this is the important bit, before making any changes to your BCU (body control module) make a back-up copy first so you can always restore it to the original state. Regards |

So, a quick update.
After connecting both pins witj a wire and even trying with a drop of solder, the cable from my friend didnt work. TOAF said it connected with the com port (even with the obd 2 disconnected) but could not foud any module (bcu, engine, etc). I've ordered an blue obd2 vag cable, but it's going to arrive at the end of this month. Until then... I'm locking and unlocking with the key in the door. I will keeo you guys updated. Thanks a lot for your help. |
