Frequently Asked Questions

If you want to make a duplicate key for one of the TESA ASSA ABLOY cylinders or for a master key system, there are two possible scenarios depending on the type of cylinder:

1- Key for a proprietary cylinder: In such cases, you must visit one of our authorized dealers and present the ownership card included in the original packaging. You can find the TESA ASSA ABLOY authorized dealer nearest to you at the following link: Dealer locator.

The patented key models are TD5, ST6, TD60, T70, ST8, TK6, TX80, and TK100; duplication of these keys is protected by the ownership card. You can identify the cylinder model using this ownership card or even on the key itself. It is important that you keep the card in a safe place and ensure you can locate it, as it is not possible to obtain copies without it.

2 – Non-patented cylinder key: Keys for these cylinders can be duplicated at any key-cutting shop without the need to present a key card; simply presenting the key is sufficient. However, TESA ASSA ABLOY recommends having them duplicated at one of its authorized centers to ensure the quality of the duplicate. 

In a patented cylinder (TD5, ST6, TD60, T70, ST8, TK6, TX80, and TK100), it is not possible to make key copies without the ownership card. This is a fundamental component of the security protocol designed to prevent fraudulent key copying, and without the information contained on the card, we cannot manufacture a new key.

On the other hand, if it’s part of a master key system (meaning you can open multiple doors with a single key), it may be in the possession of the building manager, the property manager, or the maintenance supervisor. In that case, you should contact the appropriate person to request a new copy.

Individual customers cannot purchase directly. TESA ASSA ABLOY does not sell directly to individual customers. To purchase any of our products or solutions, we recommend that you contact one of our authorized distributors. You can find the distributors nearest to you at the following link: ¿Where to buy?

Over time, dirt may build up inside the cylinder, affecting its daily operation. To prevent this, we recommend cleaning the cylinder periodically by spraying WD-40 on the key and inserting it repeatedly to clean it. In this video, we'll show you how to do it.
