Have you lost the key to your lock bolts? Here's how to remove carriage bolts without the key, so you can save money by not having to be towed.
Steps

Step 1. See if the key to your carriage bolts might be in the glove box, in the center console, in the trunk or under your seats
It can also be under the spare wheel.

Step 2. Get your socket wrenches and see which size fits over the carriage bolts
Usually number 12 fits best. There are special caps for removing carriage bolts.

Step 3. Use the socket wrench one size smaller and put it on the carriage bolt

Step 4. Using a hammer, hit the socket wrench over the carriage bolt

Step 5. Once you have passed the socket wrench over the carriage bolt, use the ratchet to remove the carriage bolt

Step 6. Repeat if necessary
Tips
- Make sure you don't hit the rim.
- If your lock bolts are factory installed, call your car dealer for the key. If you call the dealer, ask if they have a master set of the carriage bolts so you can order the correct one. If you have aftermarket carriage bolts, you will have to figure out a way to remove them yourself.
