Testers

Testers help automotive locksmith professionals quickly check remotes, batteries and electrical components before programming or repair. The category includes remote testers for detecting transmitted signals, battery testers for checking battery condition and digital multimeters for measuring electrical values during bench or vehicle diagnostics.

Remote testing can confirm whether a key fob is transmitting before the technician begins programming or replaces components. Battery testers help identify weak batteries, while multimeters support circuit, continuity and general electrical checks. Browse Batteries for replacement stock or Key Programmers for key and remote programming equipment.
