Frequently Asked Questions
Do EASILOK locks require batteries or wiring?
No. All EASILOK locks are 100% mechanical — no batteries, no apps, no wiring. They work in any weather condition, including rain and snow, and never fail due to power issues.
Will this lock fit my door without drilling?
Yes. All EASILOK models use your door's existing factory holes with our patented axial fastening system. No new drilling required — install in under 15 minutes with just a screwdriver.
How do I know which model fits my door?
Measure the distance from the center of your cylinder hole to the door edge — this is your backset. Common sizes are 31/32", 1-1/8", and 1-1/2". Still unsure? Visit our Find My Lock guide for step-by-step help.
What is the difference between SK4510 and SK4510S?
Both are keyless deadlatches that replace the Adams Rite 4510S. The SK4510S adds an SFIC (Small Format Interchangeable Core) housing for a physical key backup or master-key system integration. The SK4510 is pure keyless with no keyhole at all.
How much does shipping cost?
Shipping is calculated based on your location and the items in your order. You will always know the shipping price before you purchase.
