2000s Jaguar XJ8 Problem Resolution: NO START, WON'T CRANK

[@glenchoitz9497]

As someone else mentioned...lube the tumblers in the switch...PB Blaster instead of WD. Go online and look up the sequence to reset the security system. For background: the keys have a resistor in them that triggers the security system to allow power to go to starter, when the sides get worn on a primary key, they don't make good contact and will not work. I have bypassed these before and I have also put a small blob of solder on each side of a key to make it work again. Get a resistance reading first or the dealer will charge you huge bucks to figure out which key/resistor you have if you ever need another new key. Since your new key is not working, but the old one is again, I would suspect worn and stuck tumblers in the lock before anything else. Another item you can check since it is an intermittent problem...most of these systems have 2 wires that connect to the back of the lock assembly...those wires turn everytime you turn the key and eventually break off, but may still make intermittent contact whenever they happen to fall into the right position. Since you have defeated your neutral/park safety switch by breaking the shifter assembly...that of course could be the problem also...wiggle the stick while trying to start and see if that helps. You can also bypass the key resistor all together by getting a resistor reading off of the key, buying a resistor of that value or +-10% and finding the two wires that come out of the steering column at the bottom and go into a connector...put the resistor across the two wires/connector going back into the vehicle harness (not up into the column)...you will no longer need a chipped key, though they still will be used, and your security system will be bypassed (Actually circuit completed with right resistor reading going to the alarm control box so completing the circuit needed)so your doorlock problem may go away at the same time.

[@DanielHuet-Vaughn]

i have had a no start no crank intermittently, and then a couple times i've also noticed what my engines cooling was fan running after i turned the key off... turns out the engine is rather quiet and running too, despite the key bing out of the ignition... both issues are cause by a failing ignition switch i reckon

[@Fixologist1]

The fan continuing to run when you turn the engine off is a feature. Mine does that too.

[@GeorgeChristofi]

What do you expect Brad? It's British! Over here in the UK it is one of those things. The keys are not powered at all, they use induction to operate in the same way as the swipe cards on door entry systems. The Key is passive and the car senses the correct rfid chip and disables the immobiliser. Sounds like your spare has been blocked out by the car and needs to be re-enabled to work.

[@stephenmitchell7915]

I just replaced the guts of my Acura key. My main key just seemed to get tired; not transmit very far, take multiple tries to unlock the door(s), etc. Backup key worked fine. After I replaced the electronic part of the key, the mechanical part had to be re-synched to the ignition, which on the Acura is really easy. At first I thought you had a parasitic drain caused by a defective relay. These things sometimes slowly leak to ground and everything in the car is dead the next time you try and start it ... even though the battery and charging hardware all seem to work just fine. In the Acura it was an AC relay sticking closed which meant I was probably working the heck out of my compressor with the clutch always engaged.

Is there a battery in the key that powers the immobiliser? If so, could be the spare is dead. Or if a chip, could it have been affected by a strong magnet on the safe?

the not shifting is prob the park shift interrupt solenoid, which could be causing the no crank no start issue. Have you tested the battery in your keyfobs? Some cars rely on that to send a signal to the cars security. Might not hurt to blow out the ignition switch cylinder, but be careful spraying liquids in the lock cylinder as it can short the security switch and really cause problems.

[@davidleeroth805]

There are transponders in the keys that are coded to the ECU. If they are not recognized correctly, the car won't start. Because your car has an autosensing system to unlock the doors, i would also suspect that there is something wrong with them. For an old car like this i would recommend to buy a Jaguar diagnostic system (there are also JLR knock offs) to read the DTCs and check what is wrong. Maybe guys in a Jaguar forum can help.

[@tamarascharck6927]

Thank you! You need a mechanic like mine! Find someone who has been in business a long time, independent shop, cheap and reliable.

[@richardshort3914]

The key has a transponder. It 'reflects' a startup code back to the car, indicating it is coded to that specific vehicle. Try this first: Try to start the card with the 'bad' key while holding the 'good' key in the same hand. If it starts, the system is reading the 'good' key your transponder is defective or missing. If defective, you can have it reprogrammed by the dealer, or any competent locksmith that specializes in automotive repairs. If missing: Look for a small, round indentation at the top of the key, about the size of a pencil lead. If there is a tiny hole, the transponder has fallen out. (I have never heard of this happening, but I suppose it's possible.) Tibbes keys are available online, complete with a 'generic' transponder. You'll have to have the key cut by the specialist before it's sent to you. (It is very inexpensive.)

[@TejasAutoSalonJasonW]

More than likely, the transponder in the spare key isnt working correctly. The key turns in the ignition tumbler because its mechanical. But, my educated guess is the chip in it has lost it's pairing with the receiver in the dash. I had a similar problem with a 2001 XJ8L. Had the keys reprogrammed and it was gravy afterwards. Also, coolant and washer fluid is cheap. Take care of your ride and it'll take care of you.

[@mooseteets]

i had to do this to our car when i replaced the battery, it wasnt paired with either key as it had lost its memory

[@chrisbarrett5132]

There's no battery inside. There is a passive transponder and yours is broken. A jag dealer can cut you another key using the working key.

Ground issues brad, ground issues, all Jags use a cam bus that sends command based on resistance, once the grounds points start deteriorating the cam bus does not the codes correctly, same for doors and several comfort systems. The Spare key does not have the chip or its damaged, you need to replace it, you can't fix the chip itself (it's tiny) so clean the ground points (same issue you get with cold solder joints)

[@Tailracehero]

There's a chip in the key, that is matched to your car. I think your 'host' of problems comes down to the engine management light which is on. There are obviously some issues with it. Best thing is to take it to a dealer or a garage that you're happy with and get them to put their laptop on it, and reset the codes. I think then, you will probably find that your spare key which came with the car, will most likely work . . .Good luck!

[@sizzlechooch]

It probably has something to do with the shifter. I dont think it's the factory key. I'll bet the computer is telling the ignition(when using the factory key), that your car IS NOT in park. Try wiggling the shifter in the park position while turning the key. A good mechanic would know. Just call around

[@MrBrymstond]

I'm in NY, so when I went to Florida a few years back, my motel had RFID card for the key to get in and if I had too close to my phone when my NFC was on, the card would not work and it cleared the card. Reset the codes or disconnect the battery and press on the brake to get rid of any electrical charge the reconnect it. The key may have to be re-programmed.

Could also need a new switch behind the lock but I don't know why it would work with one key and not another, that's why I think the rfid chip is the first place to look. There is a youtube of a taxi mechanic saying he has replaced 10 of the key switches recently and it is an easy fix.

[@alanmaier]

Brad, you know how electronics work when they get old - grounds go bad. I suspect you have a ground issue at some point, possibly intermittent, and the ECU is not sensing signal correctly. That could explain the low coolant level, low squirter juice level, RFID transponder having sensitivity issues (the possible cause of one key not working) and so on. I'd pull the ECU harness and look for corrosion. I bet you are going to find a common cause for a lot of the electrical issues. Good luck!

[@toddhamm3547]

The back up key probably needs to be reprogrammed. You can find how-to instructions on youtube. Also, since it's a back up key the battery may need replaced. There is a battery in the key fob and possibly in the key itself. If it's the battery it may not need to be reprogrammed. I wouldn't boil it though.

[@bullwhipjohnson8247]

Don't boil the key. Why do you think that would help? Check the Date on the Battery. If it's a 1,3 or, 5 year Battery and the times up, Replace it before it gets any Colder. Old or Expired car Batteries never work any better in the Winter. If it's still got life left in it, check the voltage right across the terminals for reference. Next, check with the engine to read the difference when the Alternator is running. Battery should be 12+vdc if it's good. With the Alternator runing it should read at least 2volts higher. 13.5 to 14+vdc. If those are good, you need to get an engine diagnostics module and read the error codes to find the problem. It helps if all of the known bad or disabled sensors are repaired/replaced before testing. That way you won't waste time chasing those down. Since, everything is read by the EMS or Engine Management System. Eliminating known faults will only save time. And, the actual problem will be more obvious or apparent. Good Luck!🍀

[@bullwhipjohnson8247]

Meant to say, with the Engine running check the Battery again. Also, the Key Fob probably has a Watch Battery in it. Check that before Boiling.

[@Fixologist1]

You’re confusing the fob with the key. Fob works. Key doesn’t. And it obviously isn’t the battery. Engine starts fine with the other key.

[@bullwhipjohnson8247]

I'm not confused at all. Cold weather is a test for batteries. Just like extreme heat tests your AC. So far this year I've seen below 0°F wind chills. If, your battery hasn't reached it's life expectancy? And, you've had to charge it? Your alternator is suspect. It's a simple voltage check with engine running and engine off. Takes 2 minutes to find out. That's easier than being stuck on the side of the road in your pajamas in -0° weather. The key looks like it probably has a chip in it. You can go online or phone a dealer to find that out. And, why it's not working. Getting sufficient power to all of your control modules, sensors and, accessories might clear a lot of your error codes. Think of them as alarms instead.
