The PMKEY is a double bit key listed in the HMEIN Series for the standard double bit escutcheon. Because standard HME door hardware is an escutcheon plate with double bit insert, this is the key facilities teams and technicians use to open HME doors that still carry the standard insert.

A variety of other inserts (and matching keys) are available as alternatives to the standard hardware; the PMKEY covers the standard double bit profile rather than the double bit w/3mm pin, square or triangle profiles.

Hammond lists the key with dimensions of 3.5 in x 1.97 in x 0.55 in (89 mm x 50 mm x 14 mm). Its short description is KEY FOR PM ENCL 204-0108.

The PMKEY ships in a bag with a shipping weight of 0.1 lbs (0.05 kg) and is REACH and RoHS compliant, making it a simple spare to keep with maintenance kits.

The HMEIN Series lists inserts and matching keys for 7 mm and 8 mm square, 6.5 mm, 7 mm and 8 mm triangle, double bit w/3mm pin and standard double bit profiles, plus a slot coin proof insert and a non-locking insert for the HMEHLKL lift handle, so profiles can be chosen per cabinet. For purchasing and inventory records, the PMKEY is identified by UPC 623980444420 and UNSPSC code 39121321.
