EASILOK SK1850 vs Alarm Lock: Honest 2026 Comparison
Share
Quick answer: The EASILOK SK1850 and Alarm Lock's Trilogy narrow-stile lock (DL1200) solve the same problem — keyless entry for aluminum storefront doors — in opposite ways. The SK1850 is 100% mechanical: no batteries, no electronics, installs in minutes with no drilling, at a $200 price point. Alarm Lock's Trilogy is electronic: battery-powered, Grade 1 certified, with 100+ user codes and audit features, at a much higher price. Pick mechanical for simplicity and cost; pick electronic when you need audit trails and large-scale user management.
The core difference: mechanical vs electronic
This is the whole comparison in one line. The SK1850 is a mechanical keypad lock — you punch a code, gears turn, the bolt moves. No batteries, no circuit boards, nothing to charge or reboot. Alarm Lock's Trilogy T2 series is electronic — a vandal-proof metal keypad driving a battery-powered mechanism (5 AA batteries, rated around 200,000 cycles), with fingertip programming for up to 100 user codes plus managers and service codes.
Neither approach is "better" in the abstract. They fail differently: a mechanical lock never runs out of battery; an electronic lock gives you audit trails and schedules a mechanical lock can't.

Where Alarm Lock wins
Credit where it's due. If you manage a building with dozens of users and need to know who entered and when, the Trilogy's audit trail and 100+ coded users are in a different league. Scheduled lock/unlock and remote features (on networked versions) matter for facility managers. Grade 1 certification matters for spec-driven commercial jobs. The SK1850 doesn't play in that arena — and doesn't pretend to.
Where EASILOK wins
For the typical single storefront, the SK1850's advantages are hard to argue with: roughly a tenth of the price, zero batteries to change, zero electronics to fail, and an install most owners do themselves in minutes with no drilling. Code changes take seconds at the keypad. And the key is only ever a backup. See the SK1850 →
Which should you choose?
- Choose the SK1850 if: you run one or a few shops, want keyless entry without batteries or complexity, and like the price.
- Choose Alarm Lock Trilogy if: you manage many users, need audit trails or schedules, or the job spec demands Grade 1 electronic access.
- Either way, confirm your door first: narrow-stile aluminum with an Adams Rite-style prep and a 32mm cylinder hole is what both retrofit.
There's another option
Many owners comparing electronic keyless locks don't realize a mechanical keyless option exists for the same door. Before committing to a battery-powered system, look at the drill-free mechanical retrofit: the EASILOK SK1850 drops into your door's existing 32mm cylinder hole, goes keyless in minutes, and never needs a battery.
FAQ
Is the SK1850 really a replacement for an Alarm Lock?
They serve the same door type (narrow-stile aluminum storefront) but different needs. For basic keyless entry on a single shop, yes — the SK1850 is the simpler, cheaper path. For managed multi-user access, Alarm Lock's electronics are the right tool.
Does the SK1850 need batteries?
No. It's 100% mechanical — that's the point.
Can I install the SK1850 myself?
It's designed for DIY installation in minutes with no drilling, using the existing cylinder hole. Alarm Lock's Trilogy typically goes in via a locksmith or installer.
Bottom line: If your storefront door needs keyless entry and you value simplicity, the EASILOK SK1850 delivers it mechanically — no batteries, no drilling, minutes to install. If you need audit trails and a hundred user codes, Alarm Lock's electronic Trilogy earns its premium. Match the lock to the job.
