Chances are, expensive homes will have better locks than the low to mid-range priced homes. At these houses, you’ll sometimes find Baldwin locks. Baldwin locks often accept Schlage keys. Furthermore, Baldwin is another company that uses the Kwikset style keys.
There are three different grades of locks. When looking for high end commercial security, use grade 1. These costs between $115 and $400. For medium duty locks, you would use grade 2, which can be found at any most improvement stores. Grade 2 locks range between $20.00 and $40.00 per lock. Finally, the low end locks, or grade 3. Grade 3 locks run between $3.00 to $18.00 per lock.
Now we will cover methods for removing locks. To remove standard Weiser and Kwikset locks, unscrew two screws on each lock. Next remove the knob by removing the screws and pushing the latch in. At this point the knob will pop out of the door. For some Kwikset levers, you’ll need to use a small, flat-head screwdriver for the stem slot on the outside. When you slowly turn the inside thumb turn, the outside lever handle will come off as the screwdriver pushes the catch.
1) Start by removing the lock from the door
2) Next, use a flat-head screwdriver to remove the round clip from the rear of the lock.
3) Insert your key into the lock and give it one quarter turn.
4) Push the cylinder into your hand by using the follower tool in the rear of the lock.
5) Insert the correct sized pins, specified by the the tumbler guide specific to your brand.
6) Now go in reverse order from step 4, through step 1.
You can expect each cylinder to take about one minute. For more information, read “The Dollar a Minute” Locksmith by David Calvin.
