Alarm Lock HW870CRL – Frequently Asked Questions

1) What does the Alarm Lock HW870CRL actually include, and do I need anything else to finish the repair?
The HW870CRL ships as the lock case only. If your DL3500CRL needs trim, spindles, or other hardware, you reuse what is on the door or source those separately. Plan the service call around swapping the case itself, not a full lockset replacement.
2) Is the HW870CRL lock case left hand or right hand?
Left hand. The case comes pre-configured for left-hand door applications, so there is no field handing change to make on a DL3500CRL opening that is already left hand. If your opening is right hand, this is the wrong part and you need the right-hand version of the case instead.
3) Will the HW870CRL fit an Alarm Lock DL3500CRL?
That is the lock it is built for. The HW870CRL is the OEM case for the DL3500CRL series and drops in without modification, provided the door is left hand. It is not a universal Alarm Lock case, so confirm the lock on the door is a DL3500CRL before ordering.
4) Can I replace just the lock case on a DL3500CRL instead of buying a whole new lock?
Yes, and that is the point of this part. When the mechanical case on a DL3500CRL wears or fails but the electronics and trim are still good, the HW870CRL lets you rebuild the lock rather than replace the assembly. It is catalogued as a genuine Alarm Lock replacement part, so the fit matches the original.
5) I manage several buildings with Alarm Lock DL3500CRL locks. Can I stock one lock case for all of them?
No, handing splits the stock. The HW870CRL covers left-hand DL3500CRL openings only. If your doors are mixed, you need the right-hand case as well. Walk the openings and count handing before you set a spare-parts level.
6) Is the HW870CRL rated for commercial traffic or is it a residential part?
Commercial. It is built to Alarm Lock's commercial standards for access control openings in offices, schools, healthcare, retail, warehouses, government buildings, and multi-tenant residential with commercial-grade hardware.
7) Will an aftermarket lock case work in a DL3500CRL instead of the HW870CRL?
Alarm Lock builds the HW870CRL to factory specs for that lock, and using a non-OEM case introduces compatibility risk in the assembly. For a DL3500CRL you are servicing under an existing access control system, the genuine case is the one that goes back in without fitment surprises.
