When cutting a key using the dealer invoice key code, it will be necessary to know how to translate this code so it looks like the four character code that
was on the key. Once this is done, the code can be found in the key cutting guide and the key can be cut.
Dealer invoices for 1989 and 1990 vehicles display the following key code information:
The EP and ES are Chrysler's code for identifying an ignition key (EP = Primary) and a door/trunk key (ES = Secondary).
In the ignition key code (EP), the second number is 0, 1, or
2.
To translate, substitute an E. In the dealer invoice shown, EP2025, would become 2E25. If the second digit is a 3 or 4, substitute an F and EP2325
becomes 2F25.
For the door/trunk key code (ES), the first number will be 0 or 3, replace it with an L. Thus, the dealer invoice shown, ES0294, would translate to L294.
Other examples follow:
A Cherokee Primary Key Code
EP2095 = 2E95
A Cherokee Secondary Key Code
ES0102 = L102
A Wrangler Primary Key Code
EP9177 = 9E77
A Wrangler Secondary Key Code
ES3614 = L614
NOTE:
TO EXPEDITE THE KEY CUTTING PROCESS, IT IS SUGGESTED THAT THE KEY CODES STAMPED ON THE KEY SLUGS
BE RECORDED AT PRE-DELIVERY AND RETAINED FOR FUTURE REFERENCE.
