The five digit
code for the Jeep single button remote transmitter is required to
code the transmitter to match the receiver in a vehicle. The five
digit code will always be
printed on a piece of paper and never contains a 9 in
the first five digits. If the customer has the original jeep remote
transmitter, the code is located inside the clamshell case. The case
can be opened by inserting a dime in the ring corner and then pry
open similar to opening an oyster. Once the case is opened, the
printed circuit board has to be removed completely in order to read
the code. Typically customers will read the number 16019 D etched on
the printed circuit board as the code. This code is not valid for
two reasons: first it contains a 9 in the first five digits and
second it is not written on a slip of paper. When obtaining a code,
leading 0’s are important since they are part of the code. For
example, some codes are followed by a sixth digit that is typically
a different type set. In this case a code of 05534 6 is 05534 not
55346! In the event that the customer has lost their transmitter,
the code may have been written in their owners manual.
If the code has not been
recorded in the owners manual it can be retrieved from the receiver.
The code in receivers is also written on a piece of paper.
On year models 1988 and 1989 the receiver has a rectangular
cover and is located over the rear view mirror. The Jeep
receiver can be removed by gripping the left and right sides of the
lens and pulling the lens out. Once the lens is removed the receiver
can be pulled out. The code is typically written on a white sticker
on the case of the receiver. After the code is obtained, insert the
receiver back into its original position then replace the lens.
Receivers in Jeep 1990
vehicles through mid-year 1992 are typically in overhead consoles.
To obtain codes from these Jeep receivers, a Phillips screw is
removed from the console above the rear view mirror. The console is
lowered then two Phillips screws are removed from the receiver.
After the two screws are removed from the receiver, the code can be
obtained from the white paper sticker. One typical bad code obtained
from overhead consoles is 52019 B, this number is printed on the
circuit board by the wire harness. If this number has been reported
instruct the customer to remove the receiver from the console to
read the other side where the code is located. (Note that this
number, 52019 contains a 9 within the 5 digits automatically
indicating a bad code.)
There are three known
incorrect codes that occur frequently. These codes do not contain
9’s in the first five digits so always check a reported code
against the following codes. The single most common bad code is
44137. The other two bad codes are 15848 from
the newer style receiver board and 15128 from the old
style receiver board. Since these do not contain a 9 they can
represent a valid code but they have never produced a good code.
