i lost the key for my locking gas cap.... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

97guns · 07-24-2007, 05:17 PM

how should i get it off. it really didn't fit right in the sense that it didnt screw on, it just pressed on untill the "ears" of the locking mechanism engaged the lip of the fill tube. tia

BigSky71 · 07-24-2007, 05:20 PM

Is it in the stock location and made of plastic? I'd say cut the head of it off with a sawsall, but if its a metal cap that may be a bad idea!

97guns · 07-24-2007, 05:29 PM

stock location and metal. i may be able to pry it off but dont want to damage the fill tube.

i dont this about 2 years ago. i took an 1/8 inch drill and drilled out the key ways. then i took a 1/4 inch bit and re-drilled my 1/8 inch holes. then i took a straight head screw driver in the key ways and ,after some prying and manovering<spell? it came off. mine was a standard napa locking cap. and was double walled. if yours is not i wouldnt recommend drilling it out. im thinking pretty much all of them are double walled, beacause if i remember right, the lock cylinder doesnt just hang in the fill tube.... hope this may help. also you might want to try a large pair og channel locks and twist it off. i wouldnt think that it would damge the fill tube ,they are pretty stout, but what do i know..........tony

1LoC10 · 07-24-2007, 06:01 PM

call the manufactur of the cap, or buy another one and hope the keys are generic

Rdub · 07-24-2007, 06:39 PM

I also did this a couple years ago..... take a big screw driver, insert where key goes, drive screwdriver in with a hammer until it's tight, turn lock, remove cap. Worked great for me.... good luck.

When I bought the 71,it had a locking gas cap and no keys..I just drilled it out and off it came...

**Stocker** · 07-24-2007, 10:44 PM

I wonder how many different key patterns exist for those cap? Might be worth a trip to your friendly local parts store -- see if they'll let you try several keys. Might get lucky, especially if your lock is old and a bit worn.

Or just take it to a locksmith, or drill it out...

97guns,

I used to have one on the '81. My father ( retired ) borrowed the truck one day and needed to put gas in it. He did not remember that it had a locking cap even with the key on the ring ( and with his poor eyesight did not let him see the key slot - pre cataract surgery ). When he returned the truck, he did ask me why the cap was so hard to get off. He did say that he just got a good grip with both hands and twisted the cap right off - no tools involved

. He managed to bend or break the locking lugs in the cap.

I vote for just trying to twist the cap off and see what happens.

Ackattack · 07-25-2007, 12:45 AM

This last winter mine was frozen on, and I was pretty much out of gas, so I HAD to get it off. I think I just took a screwdriver to it and pretty much pried it off. It was a big PIA and took about 15 minutes.

That's hiliarious! "Damn boy you need to work on that gas cap." Strong retired guy your dad!

ChevLoRay · 07-25-2007, 11:40 AM

For what it's worth, the key to my locking gas cap (from NAPA) also works the ignition on my Cub Cadet. I put in an ignition switch from......NAPA.

72BlckButy · 07-26-2007, 08:26 AM

I had a lockable plastic gas cap on my F*** Explorer in High School, and you could squeeze, at both ends of the handle, towards the center of the cap and turn and it would be able to be removed.

^^^ +1.....I had to do the same thing worked great.

ChillFactor · 07-26-2007, 06:45 PM

Assuming the tank is in the factory location...

You could undo the hose clamp from the plastic filler tube extention that the cap locks on to and pull the cap and tube out of the truck then take a long blade screwdriver and just pulsh the locking tabs in.

Worked amazingly well on my '70.

That's my dad! Stubborn too. That little cap is supposed to come off so it is going to come off one way or another.

st1x10 · 07-26-2007, 07:28 PM

Just get some channel lock and clamp down and twist. Worked on my s10 and several other vehicles at the shop. I wish people would start leaving the gas keys when they come in for gas related things.

I'm assuming stock location is tank-in-cab. Any tank I've seen had no plastic anything. The filler neck is soldered to the tank so I would have to go with the screwdriver or drill part way through then escalate to the "bigger hammer" if that didn't work. I usually lose the gas cap and wind up with an extra key.

chip46wis · 07-26-2007, 08:56 PM

I was in the used car business for several years and ran accross this many times--------jam a blade type screwdriver in the lock and it will turn right off----did this many dozens of times.

thanks everyone - the big screwdriver did the trick

BarryB · 07-27-2007, 06:06 PM

I bought a master lock kit off the MAC Tool truck. it has a couple of picks for locking gas caps. They work to. took about 2 seconds and it poped right off. ANd guess what it didn't destroy the cap either so when you did find the key.Also unlocked several cars with it. saved me the money of calling a lock smith.

I would not recommend getting out the torches.
