Author’s Professional Opinion

From the years I have been in security and locksmith, I prefer mechanical safe lock. There are a few things that make electronic safe locks appealing such as:

  • Relative complexity
  • Ease of accessing electronics
  • No operational skills and knowledge needed to open mechanical safe locks

Normally, however, even when electronic locks fail, mechanical locks remain functional. In the same way, electronic safe locks are not well-engineered to endure lock installers or end-users. Broken power connections, spoiled keypads, and pinched data cables are very mutual. The failure of electronic locks is more today than the past shortcomings of mechanical safe locks. Though the electronic safe appears to be everywhere, they are not ready for the majority.

Cons of Electronic Locks

  • Data and power cables regularly fail
  • Replacement batteries are cheap and have a short lifespan. They tend to fail when you need them.
  • End users naturally harm electronic keypads.
  • Chemical and water damage corrodes power and electronic connections to the locks.
  • When the combinations fail, the end-users often spoil the bolt handlers. Contrary, they will try a mechanical lock first before breaking the safe.
  • Combinations in the electronic safe are straightforward.
  • Users seem to change combinations similar to the old combinations.
  • Unlike with mechanical safe locks, an electronic lock will deny you access to critical things due to the global political environment that is there currently.

Cons of mechanical locks

  • Users usually spin the dial using excess force; thus, spoiling the gate, brass wheel flys, and lever.
  • The dial rod can be easily bent, preventing accurate and smooth operation.
  • Open the lock takes a longer time.
  • Environmental locations and factors can affect the operation of the safe lock if not properly serviced and cleaned.
  • Changing the combination is not easy, especially by the end-user with no training and correct tools.
  • Duress fine-motors services fail, thus, making it hard to dial in the combination correctly.
  • The mechanical safe key is mostly lost in inconvenient times.

Addressing the cons of both safe locks will clear up the process of making your decision.

Which is better between Electronic and Mechanical Safe lock

Generally, I recommend mechanical safe lock in most cases over the electronic safe lock. I find electronic locks not to have long-term reliability.

The mechanical lock holds up well under abuse by the end-user and does not depend much on environmental and external factors. It also does not depend on fixed batteries supply. It will work even many years after installation and operates quietly. The general security of the safe lock counterweights the problems associated with ease of access.

I install AMSEC Electronic safe locks weekly and use them in place of electronic locks from other brands. These Amsec models are more comfortable to program and use, and robust compared to other similar models. They have a high demand from my customers as well as corporate management policies.

Electronic locks fit well in cases that do not require maximum operational interruption. Also, setting the combination requires just a few minutes. The safe lock has an inbuilt time delay options that are essential in theft or robbery defence, though under pressure this is not beneficial. Electronic safe locks are very useful with cash control.

In cases where many persons will require to access the safe regularly, electronic locks for controlled constituent security are excellent. I do not highly recommend them for personal locations unless the key supply is stored using a mechanism with a high-security key lock. In such a case, you can move the materials needed for a static period to electronic storage. Then you can resupply them through authorized personnel.

For short-term requirements that need to be accessed daily, electronic safe locks are the best. On the other hand, mechanical safe locks are great when it comes to long-term operation due to its reliability and capacity to function even when everything else fails.

Therefore, with the two options and their cons and pros, you can now make a well-informed decision on what will suit you well.
