For those with door keypads is your combination similar in any way to the last five digits of your VIN#? Mine is. Not in the same order though. The last five digits of my VIN# are all in the keypad combination. For example last five of VIN are CCCFE and my combination is FCCCE.

 

Just coincidence.

 

Yep! A numeric anomaly.

Mine is not close to the VIN, but coincidentally the first 4 numbers are the same as the pin on an atm/debit card I have. This made it easy to memorize!

Mine is not related.
