How Door Locks Are Tested

When you are looking to get a high-security lock for your residential or commercial needs, you would expect to get a tested and trusted product. Knowing about the testing procedure of most locks will give you an insight about the performance of the door lock.

Right from the manufacturers, door locks are categorized into three grades namely;

  • Grade 1
  • Grade 2
  • And Grade 3

The Grade 1 door locks provide the highest level of security followed by the Grade 2 lock, which is in the middle and just secure enough for residential doors. Grade 3 door locks give lower security and are just okay for locations with minimal security threats.

It is important to note that although most of the products in the market are certified, it does not mean they were tested the same way. Testing a deadbolt and the process of testing a panic bar is different. In this article, we will be exploring the common methods door locks are tested.

Common Methods Used to Test Door Locks

Door locks are tested to prevent kick-in, bumping, drilling, and lock picking. The methods with which this is done include the kick-in, drilling and lock picking tests.

Kick-in Tests

The kick-in tests are performed to see how the door reacts to a break-in attempt. You can do it on all door locks. The procedure involves kicking deadbolts, electronic locks, and smart locks repeatedly until either the lock develops a fault or it withstands the force.

The engineers swing a steel battering ram at a replaceable part of the door with the deadbolt installed. The test is done a minimum of 8 times until the lock fails. The lock models that fail go through another test with a strike plate installed on a new lock model. This test improves the security of any lock.

Drilling Test

Experts do the drilling test to evaluate how well the lock can withstand an attack from a cordless drill. The drilling test aims to see if the locking plug and mechanism will be left in working order after passing through a series of drills.

Picking Test

The Picking test is done to evaluate how well the door lock will withstand bumping or lock-picking. The engineer first uses a tension wrench to apply force to the lock and then proceeds with a lock picking tool to move the pins inside the lock. If a door lock passes these three stages then it is of high security and certified for sale and installation.
