hey everyone,

i've just bought a 2004 c-max and have a couple of questions....

1. the car only came with one key (thats all the garage had from the previous keeper) and i want to buy a spare. i know if i go to ford it will cost 100+, so i'm trying to find a cheaper alternative. i've found a key cutting place that says i can get a spare cut for 45 (minus the remote central locking) and it'll work fine, but i was under the impression that it would need to be coded to turn off the immobiliser. is this the case? i've seen on ebay people that sell coding instructions but are they actually needed?

2. there was no manual with the car, and i'm trying to figure out the air con. is it just a case that you push the button and cold air comes out, or do i have to set the temperature dial too? with the weather at the moment i can't work out if its just cold air coming in from outside or whether the temperature dial is involved with the air con function too.

I'd go back to the garage and find out where the other keys are.....

I'm pretty sure you should have a RED key as that is the one the holds all the codes for the and is used to programme new keys.

what would worry me is that potentially someone else has a key that could be used to open the car. Don't mean to worry you about that.

I'd be wary of getting things like coded keys etcfrom flea-bay though.

I hope you get it sorted.

Hi Wello listen to what Roy says about the keys get the garage to supply the previous owners details and give him a ring find out what happened to the spare. The air con works with the heat dial if you have the heat turned up you get warm dry air.

Ref the key, in the same boat still!

I bought a spare flip key from ebay but have yet to find someone to cut it.
You will then need to take the key & Car to either a Ford dealer or someone with the right software who can encode the key.

I know that I can get my key encoded at non ford specialist that is cheaper than Ford.
The option is mobile outfit that "may" be able to help. You'll need to search Google to see what is available for you in your area, but I have one down here.

Did you get it from a ford dealer or an independant?If it was ford they should supply you with both key & manual at their cost.Otherwise as lazyb says get intouch with the previous owner,quick!
All the best

Just seen your post and thought my experience might be helpful.

I have just bought a new 1.6 tdci zetec (may 2009). It came with two keys , one with electronics for remote locking and one just a straightforward key that you have to stick in the lock on the drivers door and turn. The straightforward key does not switch of the alarm and yoh have to put it into the ignition switch and turn it to position II within 12 seconds if you do not want the alarm to sound.

And just to add to this as well......

There are three parts of "a key"
1) Remote central locking - plain keys won't have this. It can be programmed by you without the need for a 3rd party.
2) Key "profile" - the bit that you get cut that will open doors, boot, bonnet and turn off the steering lock. It can be cut by locksmiths or Ford. Or even you if you have the right machines.
3) RFID tag - a tiny chip inside the key that turns off the immobiliser and allows you to actually start the car. It has to be programmed to the ECU by a computer andonly Ford or other very specialised places can do this. In the old (and new?) foci you could do this yourself but not on the C-Max.

Roy, the old red key/master key isn't used anymore. All keyshave the same importance and when you have the ECU reprogrammed you have to have all the keys there as they all have to be loaded again in one go.


There is an air con compressor which is turned on with the button. This will then dry the air and cool it as part of the process. Then there is a heater matrix will will heat the air to the temperature specified by the dial. Set it to the coldest setting (basically keeps the heater matrix off) with the A/C on and if its warm then you need to get it regassed.

Probably too late but it's there should anyone else need the info.....
