OK so ive just bought a 2000 plate octy elegance and the keyfob had no batteries inside, so i replaced them with at looks like the right batteries but cant cross referance this anywhere, (be great if someone could confirm what batteries you have..

I tried reprogramming through my snap on modis machine and couldnt get it to work.. i only  have one key with chip and fob and one key with a cut blade..

 

when i lock or unlock i get two clunks both times...

also tried the two keys method but get no horn sound..

any help appreciated

Any ideas anyone??

Hi, I just looked and it says CR2032 3v on the battery. Mine is a 04 model mk1, not sure if our keys are the same. Its called HELLA if i am not wrong and mine is the 434Mhz version. . Hope this helps.

 

 

I dont know what the ' two keys method' is but I get one flash when i lock and two when i unlock, no sound at either.

 

 

 

 

I had 2x 2025 batteries in there. Maybe the problem thanks

My 2001 (I think the locks where changed before I bought it) has keys like that shown in post 3, and mine takes 1 x CR2032
