Types of Old Locks: Piano Lock and Bontebaardslot

A bontebaardslot is a lock that was primarily used in cabinets and doors. Especially old locks from the 18th century, which belonged to the most well-known type of locks. A piano lock works on the same principle. These locks often used an old-fashioned key, also known as a skeleton key or a key for old locks. These keys fit multiple locks.

How to Recognize a Bontebaardslot?

You can recognize a bontebaardslot by its distinctly shaped key beard. When you have lost the old key, you might consider using a lockpick set. We sell lockpick tools that are specifically designed for antique locks.

Making or Buying Old Keys

If you prefer to have a matching key, you can choose to have old keys made. You can also buy existing old keys. Especially with valuable antique furniture pieces, it is wise to opt for an authentic antique key.

How to Open an Old Lock Without a Key?

Below we explain a few methods you can use to open the lock.

Method 1: Opening the Lock with a Paperclip

If you want to quickly open your door without a key, you can open the lock with a paperclip. This is one of the simplest techniques, but it requires patience and skill. Make sure to work calmly to avoid damaging the lock.

Method 2: Use a Loper (Skeleton Key)

A skeleton key or key for old locks often fits multiple antique locks. This can be ideal if you have several old locks without keys.

Method 3: Using a Lockpick Set

With a special lockpick set, such as a Hook Pick Set or a Rake Pick Set, you can open the old lock very precisely. This method is especially suitable for old pin cylinder locks and for lockpickers with knowledge about the lock.

Method 4: Using Lever Picks

If you have a piano lock that needs to be opened, a Lever Pick will help you. Check out the Lever Picks from Multipick or our advanced 2-in-1 Lever Picks.

What if the Lock Won’t Open?

Sometimes the lock does not turn smoothly, especially with locks from the 18th century. In that case, it is wise to check if there is dirt or rust in the piano lock. If the lock is damaged, consider purchasing and installing a new lock to prevent further problems.

Prevent Future Problems

Make sure you always have extra keys. You can easily have a set of old keys made. This prevents frustration when you lose your keys again.

What You Need to Get Started

When opening old locks, it is handy to have good tools. A simple lockpick practice set is ideal for learning how to open a door without causing damage. With some practice, you can open an average antique lock within 30 minutes.
