Know the three supplied tools
Lisle lists door panel remover 35350, door upholstery remover 35400 and window/door clip remover 54960 in this set. Those part numbers make the contents more meaningful than a generic three-piece headline. Check which profile matches the fastener and how it supports the panel before applying force.
Bent handles and stepped cut-outs
The documented geometry provides different access and fastener-contact arrangements. The useful question is whether the tool can bear around the actual clip without concentrating force on fragile trim. A tool fitting behind the panel is not enough; identify the fastening method and any hidden screw or release that must be dealt with first.
Metal tools need surface protection
This is not an all-plastic no-mar kit. Protect visible finishes and stop if the tool cannot engage the intended fastener correctly. A damaged or brittle clip may need replacement even with an appropriate tool. Do not present the set as a promise of damage-free removal on every age and type of interior.
Separate clip work from seals and leverage
The 31750 picks provide fine pointed access, and Mayhew 61366 addresses appropriate mechanical levering. Their different contact shapes are the reason to keep the hand-tools guide grouped by function. The 35440 is a targeted addition for supported fasteners rather than a universal replacement for every panel and trim tool a technician may eventually need.
