Replace a gate lock

A lock located outside will often tend to seize. The simplest solution is to change it to replace it with a new one. Do not waste time looking for an identical one and choose a similar or similar model. To release the parts, use a good stain remover or a soldering lamp if they are really blocked.

Necessary material

  • Pin punch
  • Screwdriver to hit
  • Drill
  • 4 mm bit
  • Step milling cutter
  • Long-nose pliers
  • Phillips screwdriver
  • Clamp
  • Soldering lamp
