The biggest advantage of a mechanical digital lock is reliability. Because they don't use batteries, Wi-Fi, or electronic components, they never run out of power or suffer from digital glitches.
This makes them perfect for gates, sheds, or rental properties where you need secure code access without the hassle of changing batteries or managing software updates.
Yes, in most cases, we can rekey your existing mechanical locks.
This process involves changing the internal pins so that your old keys no longer work and issuing you a new set of keys.
It is a cost-effective way to restore security if you’ve lost a key or moved into a new home, without the expense of buying brand-new hardware.
Deadbolts are recommended because they provide a much higher level of resistance against forced entry compared to standard spring-latch knobs.
A deadbolt extends a solid steel bolt deep into your door frame, making it extremely difficult for an intruder to kick in or pry open the door.
For maximum security, we recommend installing a high-quality deadbolt on all exterior doors.
While mechanical locks are very durable, a little maintenance can help them last even longer.
We recommend lubricating the keyway once a year with a graphite or silicone-based lubricant (never use oil or WD-40, as it attracts dust) to keep the movement smooth.
If your lock feels stiff or "sticky" when turning the key, give us a call; it may just need a quick service or adjustment rather than a full replacement.
Yes, mechanical locks are often the best choice for exposed outdoor areas.
Because they lack sensitive electronics that can be damaged by moisture or salt spray, high-quality mechanical locks (especially those made from marine-grade stainless steel or brass) are exceptionally weather-resistant.
They are the ideal solution for garden gates, boat sheds, and coastal baches where electronic locks might fail.
