Supplies and Tools: 
Cordless drill with Phillip bit
Defiant Deadbolt kit new
Screwdriver flat-end
Silicone lubrication

Mr. Bothem home is located in Upland, California. Mr Bothem purchased new locks for his home. We talked and decided it was time for new locks. Now that the deadbolt was replaced the bottom lock needed cleaning. It was full of dirt and grease. To complete the door a simple cleaning was done to get the lock to work again. A Defiant deadbolt lock was installed temporary until the actual deadbolt that came with this door was returned from the locksmith.

This post shows the six steps to replacing a hardwood front door Defiant dead bolt lock.

Step 1: Fig.1 shows the bottom lock is stuck inside the deadbolt mechanism and needed cleaning.

Step 2: Fig.2 shows the deadbolt instructions that came with new set. Read the instructions to the new deadbolt that was provided. This deadbolt is only a temporary lock which does not match the existing lock. The old lock was at a local locksmith being re-keyed to a new key.

Step 3: The old deadbolt assembly was removed by first removing two deadbolt face plate screws located on the side of the door. Once removed, two large screws need to be unthreaded from the lock. Removing the lock is easy just 4-screws. Putting it back together is much harder.  
Step 4: Fig.3 shows the deadbolt completely removed from the door.

Step 5: Fig.4 shows the parts: 4-screws, dead bolt, face plate and upside down cylinder cover.

Step 6: Fig.5 shows the wood door has a new deadbolt inside the door. Notice to make sure the top part is placed upwards not downwards.

Step 7: Fig.6 shows the bottom inside door had the handle door knob removed. Silicone lubrication was used to clean the dirt and grease from the lock face plate so the mechanism would move freely.

Step 8: The slot on the door knob allows the removal of the door knob. Fig.7 shows the push in the pin with a flat end screwdriver and the door knob can be pulled off the metal shaft.

Step 9: Fig.8 and fig.9 shows the knob needs to be align with the metal shaft pin to be placed back on and working. If not the door knob will spin but it will not operate the door.

Step 11: Directions: Fig.11 shows the cylinder (with key) into the of the polished cylinder and around the adapter plate the thin metal flat pin inside the cylinder guard needs to the threaded inside the deadbolt slot and into the interior thumblum rose assembly (handle on the other side). This must be done with two hands, one holding the lock together and the other using the Phillip screwdriver screws into each part of the lock. Now this door is safe again.
