Hidden Key . . .
#1
![Default](/forum/images/icons/icon1.gif)
Looking to hide a key on PURRRLL in the event I lose my primary key when I'm out and about. Always had an extra key on all of my vehicles cause one never knows what happens.
My solution, after a great deal of thought, is that it must be a DEAD key, i.e. no battery as that would make the vehicle "live" all the time but include the oldtime key to get you in the car and then use the DEAD key by inserting it into the slot.
My question is will this allow one to enter and start the car without providing easy access to anyone else.
Secondarily, what has everyone done to have a "hidden" key on the vehicle to allow access and starting in the event of a normal key loss. Thanks.

It's not something I had previously thought about, but I like the 'dead' key idea. But I'd probably hide it somewhere inside the car (under the hump between the rear seats, behind the pull out rear cushion with the fuse panel, etc.), and then carry the small cut-key in my wallet (where I currently carry the wallet-key for my Lexus).

Store the cut-key in a magnetic box outside to allow access and then use the "Dead" key once access is provided to start the car. Looks like a plan so far.
P.S.
I, too, thought the "cut" key only allowed access to inside the vehicle. Does it start the car as well? Something new to me.

Under the rear of the car there is a "tie down" bracket in front (rear of car) of the muffler. It is made out of steel so a magnetic box or key holder will stick to it. Also if you are a little creative you can make a box that could slide into this area.

If you quickly put the key without the battery into the slot, does the alarm go off before you start the car. Have you tried to start the car without the battery installed but with the key in the slot? Thanks.

I just reread the owners manual regarding starting the car in an emergency situation (with a dead remote battery for instance). You need to do the following:
Irregular operation
If difficulty is experienced with remote keyless
entry, keyless entry, keyless starting or Jaguar
Smart Key operation, it may be caused by:
• Internal battery low voltage. Replace the
battery. See 18, CHANGING THE REMOTE
CONTROL BATTERY.
• High levels of localised external electrical
interference, e.g. a radio transmitter.
Until the Jaguar Smart Key battery can be
replaced, or until the vehicle is outside the area
of electrical interference, the Jaguar Smart Key
should be inserted into the starter control unit.
See 15, DOCKING/UNDOCKING THE JAGUAR
SMART KEY.
DOCKING/UNDOCKING THE JAGUAR
SMART KEY
Docking the Jaguar Smart Key
During normal operation, it is not necessary to
dock the Jaguar Smart Key. However, if the
unlock button on the Smart Key fails to operate
and the vehicle has been unlocked using the
emergency key blade, it will be necessary to
dock the Jaguar Smart Key, to deactivate and
disarm the alarm system.
1. Lift the lid of the center console stowage
compartment.
2. Slide open the cover of the starter control
unit.
3. Insert the Jaguar Smart Key into the recess
with the emergency key release button
facing forward.
Note: This is not a Jaguar Smart Key internal
battery recharging procedure. The battery is
non-rechargeable.
Undocking the Jaguar Smart Key
Ensure the engine is switched off before
undocking the Jaguar Smart Key, otherwise
damage to the Smart Key may occur.
To remove the Jaguar Smart Key from the
starter control unit:
1. Ensure that the vehicle is at rest with the
gear selector in the P position and the
engine not running.
2. Carefully depress the Jaguar Smart Key
and release. The key will eject into its rest
position.
3. Remove the Jaguar Smart Key from the
starter control unit.

Started looking today to pick up an extra fob, to use as a 'dead' key, hidden somewhere in the care, while I carry a cut-key in my wallet.
Discovered that as the owner of an '07 XK, I need to be careful about the fob I purchase, as there were 2 models that switched with VIN B12814.
C2P17152 for earlier cars, and C2P17155 for later cars
(the owner of B12814 will have to be extra careful
).
Since I have an earlier VIN, I have to narrow my search to the C2P17152 model, provided the seller knows what they have, and I need to make sure it has been unpaired from the car it was used with... otherwise bite the bullet and buy a new one for ~$150 from a parts seller. And then pay to get it, plus my originals, reprogrammed...

I guess if the used fob works wirelessly, once you gain access with the cut key to the vehicle, you could install a battery and then it would start your car. New fobs are outrageously overpriced, but it may be the best overall solution vs getting a used one and finding out it doesn't work properly because it can't be programmed to your car.

Thanks to everyone for their help. I now have an extra key set on the vehicle to allow entry and to be able start PURRRLL in the event of a lost key fob.
The solution was to put the cut key in a magnetic box affixed to the steel plate (thanks jagtoes) at the rear of the car. Utilizing the cut key I can gain entry to the trunk where the "dead" key fob is located in a very secure spot. The styrofoam block holding the spare tire has a handy spot to safely hold the key fob. The "dead" key fob inserted into the slot will start the car and silence the alarm. I put a battery in the glove box so that I can make the "dead" key "alive" if I'm on an extended trip.
Again, thanks everyone. Now, if I can only find someone to cut an extra blank key I have.

On my Segway glide home, I'll check ACE, but I highly doubt they have the high tech equipment to do the laser cut.
Thanks for your input.
