Program a transponder key

Hello Jennifer Jackson...

No... even LINCOLN windows are harder to break
(sorry... your LINCOLN is pretty secure).

Worse... the best price I've paid to get a double sided
PATS (passive anti-theft system) key cut = $6.

Bring your own key... But this was all about the price of PREVENTING your current situation... (oops).

If your ONLY key is truly "inside"...
Your goose is pretty much cooked... The cost of
the LOCKSMITH is pretty trivial compared to your
alternatives... Dealers will zing you MUCH BETTER
than your "expensive locksmith"...

But what ever you do... (my recommendation)... Since
you prefer not to be prepared... (no door code or FOB)
Don't pass on the opportunity to have that same SMITHY
at least tell you about your door code POSSIBILITIES
or at least program a remote FOB for you ...

A RESPONSIBLE "expensive locksmith" will
explain the WISDOM of NEVER having less than 2 (TWO) transponder keys. (by reading your owners manual you can program the FOBs yourself (FREE).

How do you manage the "no" keyless entry...?
I remain pretty sure the number pad... & KEY FOB
(wireless transmitter) were standard equipment...

2 SPARE keys minimum... ALWAYS.

When a PCM (JTEC) and the SKIM are replaced
at the same time, perform the following steps in
order:
(1) Program the new PCM (JTEC).
(2) Program the new SKIM.
(3) Replace all ignition keys and program them to
the new SKIM.
PROGRAMMING THE PCM (JTEC)
The SKIS Secret Key is an ID code that is unique
to each SKIM. This code is programmed and stored
in the SKIM, the PCM, and the ignition key transponder
chip(s). When replacing the PCM, it is necessary
to program the secret key into the new PCM
using the DRBIIIt scan tool. Perform the following
steps to program the secret key into the PCM.
(1) Turn the ignition switch to the On position
(transmission in Park/Neutral).
(2) Use the DRBIIIt and select THEFT ALARM,
SKIM, then MISCELLANEOUS.
(3) Select PCM REPLACED (GAS ENGINE).
(4) Enter secured access mode by entering the
vehicle four-digit PIN.
(5) Select ENTER to update PCM VIN.
NOTE: If three attempts are made to enter secured
access mode using an incorrect PIN, secured
access mode will be locked out for one hour. To
exit this lockout mode, turn the ignition switch to
the ON position for one hour, then enter the correct
PIN. (Ensure all accessories are turned off. Also
monitor the battery state and connect a battery
charger if necessary).
(6) Press ENTER to transfer the secret key (the
SKIM will send the secret key to the PCM).

(7) Press PAGE BACK to get to the Select System
menu and select ENGINE, MISCELLANEOUS, and
SRI MEMORY CHECK.
(8) The DRBIIIt will ask, “Is odometer reading
between XX and XX?” Select the YES or NO button
on the DRBIIIt. If NO is selected, the DRBIIIt will
read, “Enter Odometer Reading (From I.P. odometer)”.
Enter the odometer reading from the instrument
cluster and press ENTER.
PROGRAMMING THE SKIM
(1) Turn the ignition switch to the On position
(transmission in Park/Neutral).
(2) Use the DRBIIIt and select THEFT ALARM,
SKIM, then MISCELLANEOUS.
(3) Select PCM REPLACED (GAS ENGINE).
(4) Program the vehicle four-digit PIN into SKIM.
(5) Select COUNTRY CODE and enter the correct
country.
NOTE: Be sure to enter the correct country code. If
the incorrect country code is programmed into
SKIM, it cannot be changed and the SKIM must be
replaced.
(6) Select YES to update VIN (the SKIM will learn
the VIN from the PCM).
(7) Press ENTER to transfer the secret key (the
PCM will send the secret key to the SKIM).
(8) Program ignition keys to the SKIM.
NOTE: If the PCM and the SKIM are replaced at the
same time, all vehicle ignition keys will need to be
replaced and programmed to the new SKIM.
PROGRAMMING IGNITION KEYS TO THE SKIM
(1) Turn the ignition switch to the On position
(transmission in Park/Neutral).
(2) Use the DRBIIIt and select THEFT ALARM,
SKIM, then MISCELLANEOUS.
(3) Select PROGRAM IGNITION KEY’S.
(4) Enter secured access mode by entering the
vehicle four-digit PIN.
NOTE: A maximum of eight keys can be learned to
each SKIM. Once a key is learned to a SKIM it (the
key) cannot be transferred to another vehicle.
(5) Obtain ignition keys to be programmed from
the customer (8 keys maximum).
(6) Using the DRBIIIt, erase all ignition keys by
selecting MISCELLANEOUS, and ERASE ALL CURRENT
IGN. KEYS.
(7) Program all of the ignition keys.
If ignition key programming is unsuccessful, the
DRBIIIt will display one of the following messages:
² Programming Not Attempted - The DRBIIIt
attempts to read the programmed key status and
there are no keys programmed into SKIM memory.
² Programming Key Failed (Possible Used
Key From Wrong Vehicle) - SKIM is unable to program
an ignition key transponder due to one of the
following:
² The ignition key transponder is faulty.
² The ignition key transponder is or has been
already programmed to another vehicle.
² 8 Keys Already Learned, Programming Not
Done - The SKIM transponder ID memory is full.
² Learned Key In Ignition - The ID for the ignition
key transponder currently in the ignition lock
cylinder is already programmed in SKIM memory.

if you have the battery handy , replacing the old immediately should not alter the programming
the program will not hold indefinitely but replacing is a may be 30 second job and most key fobs hold the program for a minute

with a new pcm you need to have a lock smith come and re program the key for the transponder to the new computer

It is probably the transponder bypass. Try this: Put a key in the ignition (do not turn on or to acc, just put it in) and hit the remote starter remote. If it starts, your transponder bypass is bad. I had this same problem. I have not been able to find just this part from Chrysler (you might).

You can purchase two types of bypasses. One actually uses a transponder key inside. The other is a computer chip that is programmed just like the transponder key. Your choice. Just do a search for "transponder bypass" and do a little research.

I used the TBKIII. Key & unit added up to $21.00. However, it only works with remote start. If I try to start with the key, it shuts down because it is picking up the key and the key in the bypass. Unit has a bypass for this, but I still have not found the correct answer to make it work. Good luck.

This means that the programming of the Transponder Key has been corrupted or the Programming data of the Key in ECU ( Electric Control Unit ) has been lost or not responding. You now have to get a new Transponder Key. You can get it on E-bay for $30. After you receive it, reprogram the car to the New Transponder Key to the ECU ( the process in usually given in the instruction manual or in the Service Manual ). Then the car will start perfectly.

you will need the dealership diagnostic tool to program the remote

you have to tow car to dealer - then they cut and program key - yes,it is a bit pricey!
internet offers ways but will only work couple times - repos do same thing
