Want to find 2013 lincoln mks personal entry code or SecuriCode

There is a default code stored in the PCM. You can set your own personal code but the default code will always still work. You might be able to get if from the dealer with VIN, or they can fetch it out of PCM with a scan tool. You will probably have to take car to dealer, to show proof of ownership. They don't like to do that on the phone, not to mention a fee.

I had to find this for my mkx when I purchased it used. The dealership wanted to charge me bigtime. I found this. Lie with your head in the driver side foot area. Look to the side and there is a fuse box. Using a flashlight, there is a sticker with a 5 digit code stuck within the area, (may have a letter after it, disregard this) That is your door entry code.

Agreed. I found my 2014 Lincoln MKS ecoboost securicode in the same manner. It’s as clear as day to see the sticker mounted on the left side wall of the driver seat footwell if you remove the lower molding that encompasses the hood latch release and passenger compartment fuse box, as this molding runs along the entire driver footwell. Then push the driver seat all the way to the rear position so you have enough room to contort your body and head into the foot pedal well. You can’t miss it. If you still can’t see it, recommend turning your phone on video mode with constant light flash and move the phone around the area in vicinity of driver side fuse box and eventually the video will catch the sticker with the 5 digit code or 5 digit +1 letter which you obviously ignore.
