98’ V70 2.5T Ignition Barrel Swap Issues

skii

Hello everybody,

Is anyone aware of issues that would prevent me from swapping an ignition barrel from another 98’ vehicle into my own and just using the key from said part to start the car seperately.

I have had a broken tumbler for months and have exhausted many options, New part (VIN specific) would be upwards of a grand (including shipping), locksmiths that i’ve called wont touch it.

So i decided to rip the old one out , swap an ebay part over and now it cranks but no start from the immobiliser, scanned it (dealer tool) and supposedly have a broken antenna which I hope allows me to either straight up start it or program it at the least but thought i’d seek help before maybe moving on unfortunately.

Cheers

You can cut the chip out of your old key and tape it to the antenna. That's the only easy way to do it. Programming keys on a 98 requires a really old dealer scan tool.

I work at a dealer, so no issue on the scanner, I replaced the ignition barrel antenna after the scanner said transponder was faulty. Tried starting and also reprogramming to no avail. Perhaps, I clear codes and retry as I supposedly heard used keys cant be recoded to the immobiliser. Also aren’t 97/98 builds pre-chipping?

I’ve also started to consider maybe fuel might be a factor in no start, but doesn’t explain why I cant program the key to the immobiliser with the dealer tool (correct Multipro chip and everything so definitely the right scanner)

Ended up clearing codes, tried adding a key and confirmed they are a one time as per scanner. once programmed they are locked to whatever immobiliser they are coded too. Will order new key, cut it and try to program it. Should work but cant be sure.

Did you try what Timbo said?

Nope, went the programmed key route still no start so i’ve ruled out immobiliser. Just realised in my original post i said broken tumbler, I meant ignition barrel. But ironically happen to have a code for the tumbler switch anyway so mistakenly right perhaps. Pulled the plastic cover found the contacts had some crap on it. Will clean, use spare parts switch and see if it clears up.

Otherwise I truly dont know what is causing it as no dtc’s that i could find besides ABS for the EBD connector which gets covered in some liquid (maybe brake fluid) not sure where from but cleaning it gets rid of the dtc for a while. Im thinking start with fuel relay or sender if no start and leads pop up
