LockSHAW Locksmiths offer a FREE lock security assessment to check the quality of your locks. We recommend a 3 *** British Standard lock as these are Anti snap, Anti pick and Anti drill. The brands we use are Ultion and ABS. Having Anti-snap locks prevents easy access to your homes, if lock snapping is tried on a 3*** Anti snap lock the cylinder will NOT snap. See pictures below, you can see the difference in quality.
