Disassemble Locking gas cap
« on: June 10, 2011, 11:13:52 »
Hi All,
I have lost the key to my locking gas cap.  Luckily the standard cap was on the car at the time. 

I have got the locking tab off the rear which releases the spring and nut. 

Now for the next bolt in the picture.  How does one get this off without damaging the locking assembly or exterior chrome.

And finally is it possible to have the barrel altered to match the ignition key?

Theoritcally the barrel should slide out after this?

Thanks
Kay

ok good point.

However im still stuck.  The tech manual refers to a small hole from where the lock is released.  However i have no hole on mine.  New pic attached.

Hi Kay,

It appears as if the late-style gas cap (one key fits all) cannot be deassembled like the earlier style (3 keys; door key unlocks gas-cap) as described in the factory workshop manual.
Had the same scenario with a very similar non-chromed sedan's gas cap.
Drilled little holes into the inner part similar to the ones of the early-style gas-cap. No successs. Does not come apart.

Try Sully's recommendation.

Is the car one key does everything?
I worked on the other style cap but I have no experience with this one.
I see a fine gap between the inner and outer sections.
There might be a catch in there that needs to be released before it will separate.
I wonder if inserting a metal shim or something similar and moving it around the circumference will achieve something.

Na,
did not attempt that yet.
Myself I am also reluctand to sacrifice one in order to find out - too valuable part ... better live with the locksmith's solution ... and perhaps the wrong additional key.

But I am afraid that is the only way to go. "We" (= someone) has to cut one of these to find out how the inner and outer parts are assembled. Must be slightly different (or simpler) from the earlier type. :-\
