Hello, I just purchased a 2004 Mini Cooper S yesterday. I was only given one key and it has 2 buttons, one with a mini logo, the other with has a lock symbol. Neither of the buttons seem to do anything, so I thought I may have had a dead battery in the remote. I replaced the battery and still nothing, but the red light does appear when buttons are pressed.
I then thought it may just need to be programmed so i went through the key programming process. Closing all the doors, putting key in ignition turning to one click, then removing the key and holding the logo button down and pressing the lock button three times and releasing simultaneously. Nothing happened when I did that so I tried it a few more times and still got nothing.
After that I checked the fuses and made sure that they were all un-blown and they were all fine. I can stick the key in the door and all the doors will lock/unlock, and the switch on the inside console works as well.
I do not know what else to try, Does anyone have any ideas as to what I could check next?
Is it possible that a previous owner has trashed a key then used a secondhand fob which isn't set to your car?
I hate to say it but I think you need to go back to the seller or take it to see a BMW dealer who can look at why it's not working properly and steel yourself for the cost of paying to reprogram a new key.
Hmmm... I don't know I guess anything is possible when buying a used car. I also cannot seem to get the windows to roll down/sunroof to go back while holding the unlock button, or putting the key in the door and holding it in the unlock position. I would hate to take it to the dealer and get charged out the @$$ to get it diagnosed/fixed.
It sounds like it either needs recoding or the transmitter is dead - I don't think there is much else to try.
We had a proper key and a spare with our 1st MCS bought 3 years old. The spare had no buttons and only unlocked using the keyhole and if you didn't get it in the ignition in 15 seconds it would set off the alarm. I enquired about a new "proper" key and was quoted >£100 for the key + labour for coding to the car. I feel you pain but I can't suggest anything other than taking it to BMW and asking them to tell you costs before you pay up or decide to put up with it.
IMHO only having a single key for a car is dodgy - a pal of mine discovered a previous owner of his car was taking it for drives when he was at work. He found out when the guy picked up a ticket and it was sent to my pal. The police prosecuted him for the traffic offence and theft.
Alright I guess that is what i'm going to have to do then. I am definitely going to get another key made soon. Luckily I bought the car from a guy that lives 1hr+ away from me so hopefully there will be no unapproved joy riding from the previous owner .
