Proper lock preparation before using Original Lishi tools is essential. Follow these steps to insure that the lock is prepared properly.
Note: It is recommended that only electrical grade chemicals are used in vehicle locks. Electrical grade chemicals do not attack or damage paint, rubber, or plastics. All of which can be found in or around vehicle locks.
- Using an aerosol electrical grade contact cleaner such as CRC QD Electrical Contact Cleaner, insert the plastic straw just into the key way opening of the lock. If the lock has a spring loaded shutter, such as most automotive door locks, insert the straw only far enough to open the shutter and direct the solvent into the key way and to the rear of the lock. Flush the lock thoroughly with the contact cleaner.
- Be careful not to shave off any of the plastic tubing as you extract it from the lock. If the tube becomes trapped in the lock, use a small thin instrument, such as a standard lock pick to open the shutter far enough to release the tube.
- Insert a blank key, in the case of a non-high security lock. With high security locks, insert a key cut to all number one depth cuts (or the shallowest cuts). With both types of lock, exercise the lock by repeatedly inserting and extracting the key multiple times.
- Using canned air, available at any office supply store, insert the plastic tube into the key way as you did previously, and blow the lock out thoroughly.
- Using an aerosol electrical grade light viscosity lubricant such as CRC Heavy Duty Silicone, insert the plastic straw into the key way opening of the lock as before and squirt enough lubricant down the key way to saturate the lock.
- Once again, insert a blank key or a key cut to all number one depths or the shallowest depths and exercise the lock repeatedly, as before.
- Insert your Original Lishi 2in1 tool and without applying any turning tension, lift each wafer fully, then remove the lifting pressure while observing the lifter. Each wafer should feel springy and bounce back when you release pressure on the lifter. If any wafers do not respond in this manner, if they respond sluggishly, become lodged in the lifted position, or do not bounce back, etc., repeat the above process as required until all wafers respond properly before attempting to pick the lock.
The goal is to achieve a lock condition where all the wafers move freely, have full unrestricted range of motion, and settle completely into their naturally relaxed state when released. Using this method of lock preparation is essential to achieving consistent, positive results when using Original Lishi tools.
