Electromechanical lock, comprising electronic circuit configured to read data from external source and match data against predetermined criterion, and access control mechanism (104) comprising drive gear (502, 504) rotatable by electric power and driven gear (506, 508) meshable with drive gear. Provided that data matches predetermined criterion, drive gear (502, 504) meshes with driven gear (506, 608) and rotates driven gear such that access control mechanism (104) is set to open state. Provided that external mechanical break-in force is applied to access control mechanism (104), drive gear (502, 504) remains stationary and driven gear (506, 508) jams in drive gear such that access control mechanism (104) remains in locked state. |
