keys, you should be able too remove the whole tail section to get to thee tumbler. Question are they only getting you keys ,or and tumblers? Cause if they just get you keys don't drill anything! Lock smith can re-key everything to foy the locks. If you get both, then drill slow. You don't want slivers of metal in your fuel tank. If you remove rubber gasket on the fuel cap....around the key slot... You can pry the metal cover that had the slot cover....careful it had springs in it...you can use strong flathead screwdriver, after you drill it out, you should be able to twist it out....if you get the cap off safer to get aftermarket cap. That will save you keys!! Thats why i know this stuff.
