HPC developed Tubular Picks that work on all of the pins in the lock at the same time. This has proven to be the most efficient and effective method for defeating tubular locks. With a few pumps in the lock, the feelers on HPC tubular picks move into position and mimic the pattern of the original key. You can then decode the feelers and cut a new key by code, duplicate a key directly from the pick, and of course,open the lock. HPC offers 3 different models for use on 7-pin standard tubular locks. A genuine leather case (No. TLP-CASE) and the Tubular Key & Pick Decoder (No. TKPD-1) are included with each model.
