The 'Glass Tube Key' is a tiny glass tube used as an alternative key ('user key') for the mo.Lock RFID ignition lock.  

Please note the possible significantly reduced operating range in comparison with the Teardrop Keys (5-10 mm). Furthermore, the operating range is subject to wider tolerances.

A maximum of 3 keys may be associated with one mo.Lock at the same time. For teaching additional keys the associated 'master-key' to the mo.Lock is required.

Some extra info about the mo.Lock
Motogadget mo.Lock RFID Ignition Lock. Yeah, that is pretty high-tech cafe racer stuff! No hassle with keys, but just walk towards your bike and start it! Only make sure that your keychain is about 40-50 mm from the mo.Lock.

The mo.Lock is a contact-free digital ignition lock with RFID technology and substitutes mechanical ignition locks or their electrical switching feature respectively.

The associated digital key/transponder only has to be approached to the mo.Lock (switching distance approx. 40-50 mm) and the ignition is switched on or off completely contact-free.

The mo.Lock is based on the latest RFID technology (Radio Frequency Identification) and therefore, unlike e.g. radio remote controls, tamper-proof. Each key/transponder has a unique digital code. 
The mo.Lock can be actuated with the correct digital code only.  Key/transponder and mo.Lock are absolutely free of mechanical wear.
The mo.Lock switches automotive relays with a possible load of up to 40 A - sufficient power for every onboard system.

The hidden mounting of the small mo.Lock, covered by non-metallic parts like e.g. a plastic side panel, permits completely removing the mechanic ignition lock. Clean look and various design possibilities are guaranteed - especially for custom bikes!

The available option 'Glass Tube' is so small (3 x 13 mm) that it can be sewn into the glove. Please note the reduced switching distance (about 5-10 mm) of the Glass Tube transponder. The 2 included standard keys (teardrop shape) are key fob sized.

All keys/transponders are available as a replacement 'key blank' and can be 'taught' to the desired mo.Lock. 

NOTE: We do not recommend using the mo.Lock combined with immobilizers! Contact your dealer/manufacturer for information about the possible deactivation of the immobilizer.

All advantages summarized

RFID technology is tamper-resistant
Each key has a unique code
The key first activates the mo.Lock without touching it and then, via the relay, the entire onboard system
Neither key nor mo.Lock suffers from mechanical wear
The key requires no battery - failsafe
No overload or scorched pins possible due to indirect switching via the 40 A main relay
The mo.Lock is very compact an can be mounted hidden in many places
Watertight and vibration resistant because of the moulded-in construction
Depending on the model, key sizes range from very small (key fob sized) to tiny (glass vial) and may be integrated into other objects like gloves, clothing, pendants (NON-METALLIC!) etc.
Keys can be easily purchased and 'learned' to any mo.Lock - your integrated locksmith
A switching distance of 4 - 5 cm ensures convenient switching while excluding the possibility of accidental engagement
An integrated LED shows the status of the mo.Lock while mounting, connecting and 'teaching' new keys
