C5 Spare Key

[les-cumbria]

Have just got a C5 2004 (Mk1) estate diesel and it only came with 1 key.

 

Fine, i thought there is a place that does the garage keys - (one without the blip) a few miles from me.

 

I am at the moment trying to sell my 05 Picasso which ive put on ebay and as i have a full tank of diesel and the insurance change does not take place till next weekend, my plan was just to use the picasso till then plus im legal driving it to show potential buyers the car etc.

 

So took the key to my local place (keyishoes) and yep no problem can supply the garage key and program it £60, ok I'll have one - "need to have your car here sir!!"  

 

my question is why does he need to have the car because when i bought the picasso I had a key cut and programmed (same type - garage keys) without the car being there, in fact it would have been impossible to take the car that time as the supplier was in the middle of a shopping precinct.

Maybe it's to prove you own the vehicle rather than any technical reason

Did you ask why?

[les-cumbria]

no i never thought of asking but am going to take the car when the insurance kicks in, have also emailed another company and asked them the price plus do they need the car in, my wife did make a valid point yesterday and wondered if they wanted to sync the key with the car but not sure whether this is done on the mk1

Here's my (long winded) experiences of trying to get another key for my C5.   In the first year of having the car, I had my second plip stolen when my caravan was broken into in Spain.   That gave me a worrying three months wondering if at some point they would be back for the car.   A branch of Mister Minit cut me a new key but he explained that it would just unlock the door (and also trigger the alarm).   When I returned home, I bought a used plip on ebay and transferred the key blades.   The plip would still just unlock the doors.   Some months later my neighbour called a mobile locksmith to her house.   When he'd finished I talked to him about my plip.   He brought over some equipment to the car and eventually got the plip so that it would start the engine, but the central locking wouldn't work.   I decided to settle for the plip as it was.

 

And Yes - I can see that they would want the car there.

The following is the Citroen procedure - so it looks as if the car has to be plugged in to a Lexia.

 

Addition or replacement : Vehicle keys

C5DH07P0

Addition or replacement : Vehicle keys

 

1. Remarks

When adding or replacing a vehicle key, it is necessary to perform the following operations :

• Key programming procedure
  
• Synchronisation of HF PLIP remote controls
  

N.B. : The vehicle keys are allocated to a single BSI.

CAUTION : Initialising a new key will require all the keys to be initialised.

2. Diagnostic tools

"LEXIA 4171-T" station.

"PROXIA 4165-T" station.

3. Registering the keys

3.1. Initialisation procedure using the "LEXIA" diagnostic tool

Make the following selections in the diagnostic tool :

• "DIAGNOSIS"
  
• Select the vehicle
  
• "GLOBAL TEST"
  
• "BSI ECU"
  
• "INITIALISATION"
  
• "KEY INITIALISATION"
  

Follow the instructions given in the diagnostic tool.

3.2. Initialisation procedure using the " PROXIA" diagnostic tool

Make the following selections in the diagnostic tool :

• "DIAGNOSIS"
  
• Select the vehicle
  
• "BSI"
  
• "LOGO F5"
  
• "INITIALISATION"

Follow the instructions given in the diagnostic tool.

N.B. : The "PARAMETER MEASURES" menu can be used to check the number of keys initialised . The number of keys initialised indicates the total number of vehicle keys. The number of HF PLIPS initialised indicates the number of HF keys initialised.

4. Synchronisation of HF PLIP remote controls

N.B. : When replacing the batteries of an HF PLIP remote control, it is necessary to resynchronise the remote control.

Perform the following operations :

• Put the HF key to be synchronised in position "ignition +"
  
• Within the next 10 seconds, press one of the HF key buttons
  
• Release the HF key button
  

The ignition key HF PLIP is synchronised.

N.B. : Perform these operations for the other keys equipped with HF remote control.

Carry out a locking / unlocking test of the vehicle’s doors and tailgate.

N.B. : If the locking / unlocking test of the doors and tailgate is not correct, restart the synchronisations of all the ignition keys equipped with HF PLIPS.

most keys can be programed off car via a infa red reader. but on a c5 with a multiplexing system it has to be done with the key in the ignition and a maximmum of 4 keys alowed and a 4 digit code for unlocking the ecu. While it seemms a proper pain when trying to get a key  it does stop people sitting in car parks with infa red readers getting your key code every time you use the plimp key then coming and stealinng your car as they have the reg ( gets them a key to open the door) and the 4 digit code to start the car.
