By doing it yourself you can spare yourself some money on paying a locksmith, although we recommend to look for a professional to perform a rekey.
This DIY guide comes with steps you can follow when rekeying your deadbolt lock if you are up for the task.
DIY Rekeying Explained
Prepare your tools
A keying kit can be bought everywhere, from Amazon to Walmart. A Rekeying kit consists of: Top pins
Cap pin springs
Cap removal tool
B-series deadbolt tailpieces
New keys and instruction sheets
Other tools you need to prepare are needle-nose pliers, tweezers and a screwdriver.
A kit can be used to rekey six times. It is also specified in the instructions which type of bolts and locks the kit can be used for, so buy accordingly.
Slip the wire tool into a slit separating the knob and the rest of the lock. Instead of a wire tool, you can also use an unbent paperclip. Insert your current key into the hole and slowly turn while depressing it. The knob will come off.
Remove lock cylinder housing
Remove the knob sleeve from the back of the knob and take off a cylinder-shaped object. That is your cylinder housing.
Remove retainer ring
Encircling the hole to which you insert your key is the retainer ring. Hold this retainer ring against the gap in the retainer ring tool and pop it off. A retainer ring is the tool that looks like a wrench. Also, put away the retainer ring for when you reassemble the knob later.
Remove cylinder plug
Insert your key back into the hole and turn it either to the left or the right. This will separate the top and bottom pins. Follow with pushing the plug follower into the cylinder. Keep a constant pressure because the pins in the cylinder plug might fall down.
Take out the pins and your old key from the cylinder plug. Insert a new key, and replace the pins with new ones according to the instruction sheet. Use tweezers or pliers for an easier job. The small pins are arranged based on colors or numbers.
Reconstruct the lock
Once you have inserted the new pins into the cylinder, repeat all of the processes mentioned in reverse order. That is:
Insert cylinder plug back into the cylinder
Reattach the retainer ring
Reattach the knob sleeve
Reattach the knob back to the slot
And you will have your knob that now works with a new key!
Some tips that are applicable when rekeying your lock are:
Make sure you bought the right rekeying kit with pins and keys that are suitable for your brand of locks.
Lightly oil your keys before rekeying to make sure that it turns smoothly.
Do not work in a slippery surface, in case that the pins fall out and roll away. Work in a rougher surface or a box or container that could keep them from falling and getting missing.
If the pins were accidentally removed from the cylindrical lock, do not fret, there are instructions in the information sheet in order to put them back together.
If the information sheet does not contain any order to arrange the pins, or if there is a lack of information sheet, insert the pins by trying on them one by one and seeing if they fit the key.
