This original key for GL1500 is blank, and must therefore be sharpened as the key you already have.

However, grinding is a bit difficult, as there is not much goods, to keep it in the grinding machine.

However, I myself have had a few polished in the local DIY store, after which the new key worked perfectly.

There are 2 types: Type1 and Type2:

Type 1 is the first picture, and type 2 is the second picture.

 If you don't know how to see it, please send us a photo of your original key
