Mottura Series 52J double-bit locks for security doors use the REPLAY recodable core, allowing the lock coding to be changed without replacing the complete mechanism.

Using the dedicated recoding key, the REPLAY core can be reconfigured when required, retaining a double-bit locking system while providing a practical recoding option.

Series 52J uses double-bit keys and is available with ANTIDECODUE anti-manipulation protection. The range includes rim and mortice models, side and three-point configurations, with or without latch and with reversible latch on relevant versions.

Replacement REPLAY cores and keys are available for system maintenance. Additional protection can be provided by the Mottura DF430 magnetic Defender for double-bit key openings.

Compare code and dimensions with the existing lock to identify the compatible Series 52J REPLAY model.
