PDQ I1274203 – Frequently Asked Questions
1) What does the PDQ I127-4203 cam actually do, and what housings does it fit?
The I127-4203 is a Lockwood-profile replacement cam for PDQ conventional mortise cylinders. The cam is the tailpiece on the back of the cylinder that drives the lock body, so it has to match the lock it is turning. PDQ offers the Lockwood cam for conventional mortise cylinders and small format interchangeable core housings only, not for large format housings.
2) Can I use the Lockwood cam on a PDQ large format IC housing?
No. The Lockwood cam, along with the Sargent standard cam, is offered for PDQ conventional mortise cylinders and small format interchangeable core housings only. If you are working with a large format IC housing you need one of the other PDQ cam profiles, such as the Adams Rite AR, Corbin cloverleaf, straight, or Schlage cam.
3) I'm replacing a cam on a PDQ KT Series deadbolt. Is the I127-4203 the right one?
No. PDQ KT Series deadbolts use the Adams Rite AR cam, not the Lockwood cam. Order the AR profile cam instead. The Lockwood cam I127-4203 is for cylinders driving Lockwood-style cam prep.
4) Which PDQ cam goes with MR Series mortise locks and 6W exit device trim?
MR Series mortise locks take the Corbin cloverleaf cam. 6W Series wide stile escutcheon exit device trim takes the straight cam. Neither uses the Lockwood profile, so I127-4203 is not the part for those applications.
5) Do I need a whole new mortise cylinder, or can I just swap the cam?
If the cylinder and keying are fine and only the cam profile is wrong for the lock, swapping the cam is the fix. That is exactly what the I127-4203 is for, a replacement cam for PDQ conventional mortise cylinders. The cam screws to the back of the cylinder, so the existing keying stays untouched. If the cylinder itself is damaged or you need a different keyway, replace the cylinder instead.
6) I'm standardizing a building on PDQ cylinders but the locks are different brands. How do I handle the cams?
You keep one cylinder platform and change the cam to suit each lock. PDQ publishes cam profiles for Adams Rite AR, Corbin cloverleaf, straight, Schlage, Sargent standard, and Lockwood, so a facility running mixed mortise locks and deadbolts can be keyed on one PDQ system and still drive each lock correctly. The I127-4203 covers the Lockwood profile on conventional mortise cylinders and small format housings.
7) Is the PDQ I127-4203 cam a genuine factory part or an aftermarket copy?
It is a genuine PDQ part, manufacturer part number I127-4203, sold as a replacement part in the PDQ Cylinders and Cores line. For commercial door hardware that matters, since cam tolerances decide whether the cylinder actually throws the lock.
