Thank you so much for the instructions. I bought a house and seller don't have the keys to the back door. I shim open a dead bolt lock and a door lock following ypur instructions. That saved me from calling a locksmith. I don't have a coreshim, but I cut up an empty Coke can and use it as a shim. Thanks again.

Found one trick that really helps - before you insert the coreshim, use a flashlight to visually spot the pin. Slowly pull the blank key out until you see a gap between the first pin and the cylinder. Insert your coreshim now and work the key slightly back and forth to get the coreshim in. Once the coreshim is past the first pin, the blank key will not insert all the way in, indicating that the first pin has been shimmed. Start to slowly pull the blank key out until you can get the coreshim to advance to the next pin. As you successfully shim each pin, the key depth will decrease. When you get to the 5th pin, use a small jewelers screwdriver to move the pin, while applying pressure to insert the coreshim past the last pin. The cylinder will start to pop out when you find the right location for the last pin. Turn the cylinder to the left or right side, push the cylinder flush and tape the front so the cylinder doesn't fall out. The lock is now set for rekeying.

The DVD security tab trick was a life-saver! I didn't expect to have to shim my lock apart, but I didn't have a key for one of the locks I was using. I was able to buy a key blank at the hardware store, but they didn't have a shim. Great tip - thank you!!

Wow, it works!

I ran out of key blanks so I used a shim and lock pick hook. Works like a charm

Thank you, I'm learning from your videos, your friend from Somalia.🇸🇴🇸🇴🇸🇴

I just got my one problem Sargent lock open with the DVD shim method - thanks!

Thanks for your videos. They are very helpful. I watched several other videos by other people but yours are by far the best.

I used the DVD shim and it was harder than you made it look but eventually got it.

I don’t know if this will help you.but I made my own shims out of a Mt Dew can. A scissors worked real well cutting The aluminum can ,so I could cut to fit what I needed. Chris

Hi Great Demo. What is the purpose of shimming the lock if you already have access to the back. Is this just so you can gut the lock?

vice video buddu good info👍😊😊😊

That lock is a defiant brand lock. sold by home depot not sold by kwikset. it only uses a kw1 key the keys are interchangeable.. if they are blank no cuts only.the key depths are different from kwikset to defiant locks. have a nice day.....

Interesting, if you want to re-key an existing cylinder and get it out, maybe if you have an antique door and wanted to keep the patina, otherwise the labor required would be worth more than the price of just replacing the lock with a new unit.

Have to use a blank? Can i use an old nonfitting key? Else inhave go buy a blank ley.

Can you tell me where you obtained the digital caliper?

Does it have to be a blank or can you use a key thats been cut? Thanks, great vids!

Too much pressure was used on the shim. Use light give and take pressure on the shim and key. Presenter said shim was good for about two locks. I get at least twenty or more locks by using very slight pressure.

What if I lose track of and/or my driver pins and springs have popped out? I have them all, but am unsure where they all go.

I knew those shims looked so familiar! I've seen people selling them and they always made me think of the security tags. Every time I mentioned how they looked like that though has gotten my comment removed.
