Keys Cut to Key Number

We can cut keys to the manufacturer's key number (often referred to as the 'key code'). For this particular blade the key number will usually be on a black plastic key tag and will start with two numbers followed by an additional five numbers, e.g. 12 01234 / 62 01234.

NOTE: The key number will not be on the key itself.

Keys Cut to Photo

If the option for 'Cut to Photo' is shown in the key cutting drop down box we can cut the key to a clear picture of the blade. The blade should ideally be on a white background with the end of the blade facing towards the right. The picture should not be blurred and the cuts of the key should be easily identifiable. You can see an example picture here.

IMPORTANT: Keys cut to key number will be cut to the original locks of the vehicle. If the vehicle has previously had the locks changed then obviously this key will not work. Keys cut to key number are non-refundable.
