Well I'm still waiting for the Security Card to get to my local Jeep Dealer !!.
Story so far....
Ran out of Diesel 16 days ago !!...dodgy sender unit, thought I had 1/4 tank !!. Managed to get some from local garage and started bleeding it through. Although turning , engine not firing. After about 20 goes (immobiliser on/off/on) etc and it was starting to fire up..(getting any air out of the line) engine stopped cranking altogether !.
Thought dodgy clutch switch (battery still OK) so by passed it...."no way Jose"! so....rang my brother who towed me home.
After 2 days recharging battery and all the usual checks, noticed the immobiliser led was staying on permanently and unable to verify the VIN.
Books it into local Jeep Dealer and gets it recovered from home to there 2 weeks ago on Thursday.
Waited for the diagnosis....6 hrs later told unable to get into the system as the immobilser has frozen and they need a security card or something to use the DRBIII and this has to be mailed from Chrysler UK.
After 4 phone calls to them over the past (nearly 2 weeks) security card still not arrived!.
In the meantime I got in touch direct with May & Scofield (great and helpful guy there called Del) who confirms that without the security card unable to unlock the frozen unit and let it find the VIN. Worst case it could be a dodgy chip in the Immobiliser (almost 15 years old) and may require new immobilser unit that will need to be paired with fobs/keys etc by dealer. I only have to match the CIS 5010 code on mine from any cherokee, the serial no means nothing.
As I'm thinking the worst, managed to track down a secondhand immobilser with the same code for £35 ....Ebay. If i didn't buy it with 2 hours to go, you can guarantee it ...as sure as hens lay eggs that I will need one.
To date....Cherokee still at dealers, Mechanic was at Head Office yesterday for training anmd will bring the security card back with him if not sent !!.
I gather, its been poor service from Chrysler UK since they went bust and have I gather been taken over by Fiat

?......
C'mon...it doesnt take 2 weeks to mail out the security card.
I'll keep you all updated on progress as I guess this may happen to others
By the way....if I order a replacement ECU from the states and remove all the Immobiliser kit and then install the ECU....will that make my vehicle non immobilised.....and no longer subject to all these problems...would be worth the expense.
Don't worry the diesel running out will not happen again !!....since found out it's a common problem. Must have been lucky filling up when I got to 1/4 tank for the past 2 months!!
An extremely frustrated HKS
