A landing gear system for a vehicle includes a landing gear configured for reciprocating motion between a stowed position and a deployed position. The landing gear has a linkage with a first link rotatably coupled to a second link. The linkage reciprocates between folded and extended states when the landing gear reciprocates between the stowed and deployed positions, respectively. A fail-secure downlock includes first and second electromagnets fixedly positioned relative to the first and second links, respectively. The first electromagnet is proximate to the second electromagnet when the landing gear is in the stowed position. The first electromagnet is attracted to the second electromagnet when the downlock is in the locked state. The first electromagnet is repelled by the second electromagnet when the downlock is in the unlocked state.
