Somfy Notentriegelung 2400658 Emergency Release Kit with Key Lock for Garage Doors and Rolling Shutters

Power failures and motor malfunctions don’t have to leave you locked out. The Somfy Notentriegelung 2400658 is a key-operated emergency release that gives you manual access to your motorized garage door or rolling shutter from outside. Unlike basic pull cords or interior-only releases, this kit puts a secure, weather-resistant key cylinder right on the door panel, so you can disengage the drive and lift the door by hand whenever the need arises.

Highlights

• Key-operated manual override for motorized doors
• External access through the door panel – no need to enter the garage
• 2.5 m steel cable for flexible routing to the operator
• Universal compatibility with Somfy Dexxo Pro, GDK, LS, Axorn, SDO and many third-party drives
• Includes 2 keys and all mounting hardware
• Robust metal/plastic cylinder in black/grey

In daily use

Imagine a storm knocks out power overnight. With this emergency release, you simply insert the key, turn it, and pull the cable to release the motor brake. The door can then be opened manually. The key cylinder is designed for through-panel mounting, requiring only a 20–25 mm hole and fitting panels up to 50 mm thick. Installation is straightforward for a competent DIYer or a professional.
