I have a jaguar x-type 2003 awd and engine will not turn over. I have checked the battery and cables. The red security light is blinking rapidly. What could be the problem

This is a network communication problem with the ECM, first check the battery voltage for a low voltage, start the car and recheck it should be about 13 to 14 volts if it is ok you may need a dealer. Good luck.

Does it click at least? Most likely battery terminals are dirty and need to be cleaned and greased. Could be security system needs to be turned off at driver's door lock, left quarter turn, twice.

1.)I would recommended that you ensure all key fobs are fitted with new batteries. ( Click here to see battery replacement guide).
2.)Get in the car and close the drivers side door.
3.)Put the key into the ignition and turn to position I.
4.)Wait 5 seconds
5.)Turn the key quickly to position II then back to I four times.
6.)You should hear a single chime.
7.)Remove the Key
8.)For each Keyfob in rapid succesion. Press any single button on the keyfob you wish to pair, you should hear a chime as each Keyfob is paired with the security system. After the chime do the next Keyfob.
9.)Check operation of each Keyfob.

You can purchase pre-programmed keys only from Jaguar. However you can purchase keys on the internet and match them to your car as follows:-

Jaguar X-Type Programming (Pairing) a Remote KeyFob X-Type 2.0, 2.5 and 3.0L



Programming or pairing a new remote Keyfob for the X Type is a very simple job that will cost a substantial amount if it is done by Jaguar. It's annoying but this may need to be done if your Keyfob battery has been allowed to go flat, or the car battery has been removed for any length of time.
Follow these steps exactly and you should have no problems, pairing old or replacement Keyfobs for your car.

1.)I would recommended that you ensure all key fobs are fitted with new batteries. ( Click here to see battery replacement guide).
2.)Get in the car and close the drivers side door.

Get the batteries replaced in the remotes. AutoZones ussually have RF meters to check the remotes for you but the cause most of the time is the battery. Their life span ussually does not pass 5 years. Good luck

You must charge the battery or you can use jumper cables from another battery to your battery to activate the electric trunk release, just be sure you hook up the jumper cables correctly ( cable to + on the battery and black to _ terminal of battery)and wear safety glasses when hooking up cables this should release the trunk. Also as a precaution always hook up + or red jumper cables wires first to prevent a arcing spark which is not terribly dangerous but this order in which to connect jumper cables is recommended.

what are the codes? let me know and could try and help

The long story short it probably your battery being dead or a computer glitch (if there is nothing else apparently wrong with the car)
One is the battery life of an older model jaguar is going to be short compared to newer models. I noticed I have problems with my battery going dead around the 6 th year of the cars life since then a bunch of silly issues. One thing to know is if your car doesn't start it (even if your lights work) is that your battery is to low for the ignition to work (which requires high voltage). You can try removing the batter than re attaching it back to the car.
I have these issues typically when i don't drive for long periods of time in the winter (mostly). The car contains a big gigantic computer (which a lot of owners do nt realize) controlling everything weather you can start the car or not (it has a security system still armed) so when the computer is not working properly or the battery is too low (and their are no other apparent reasons). I would suggest trying a few suggestions on the jaguar forum because its very specific but you would be surprised how stupid the issues end up being. Flat bed a jagaur to any dealership and your already in the hole for 150 plus.
good luck

Homelink Garage Door Opener Programming Procedure:

The procedure described below was successfully applied to a 2005 Jaguar S-Type.

To begin with, several attempts were made using the programming instructions contained in my Jaguar’s owner’s manual. Though the procedure described in the owner’s manual was straight-forward and understandable, I was unsuccessful in getting the vehicle’s remote to make my garage door opener function. The particular garage door openers I have are both made by Genie. Both openers utilize the “Rolling Code” feature.

To begin with, be sure to clear previous codes on your Jaguar’s garage door opener by first turning (rotating) the ignition key to the “I” position (first notch). Next, simultaneously hold button 1 (left most button) and button 3 (right most button) down until the middle button’s red light changes from continuous on to a rapid flash. This process takes approximately 20-25 seconds. What follows is a two part process. In the first part, get your Genie portable remote and hold it near (approximately 3 inches away from) your Jaguar’s garage door opener console buttons. Choose which button on your Jaguar’s remote you wish to dedicate to your Genie door opener and simultaneously press and hold your Genie opener button and your Jaguar’s opener button. The red light on your Jaguar’s center button (button #2) will light up and within 1-2 seconds will begin to flash rapidly. You have just completed part 1 of the two part process.

Part two: Now it is time to utilize the “Learn” function on your Genie garage door opener. Press the “Learn” button on your Genie garage door opener. The red LED adjacent to the “Learn” button will begin to flash. You now have 30 seconds in which to program your Jaguar’s opener button. Using the same button you just used in the “part 1” procedure, press and hold the same button for several seconds. As before, your Jaguar’s red light in the middle button will light up and within 1-2 seconds, it will flash rapidly. Release the button you are programming. Now, here is the key piece of information! Once again, press and hold that same button. Once again, the center button’s red light will flash rapidly. Release your newly programmed button. This procedure proved successful in my application. Here is what has just happened. The first time you pressed your Jaguar’s remote button tells the Genie opener that it exists and that it is a viable candidate for making your life easier (opening the damn door). The second time you press your Jaguar’s remote button confirms to the Genie’s rolling code that your Jaguar’s signal is legitimate and is to be trusted from then on.
