Hi, my dad bought a BMW Z3 2002 and we can not access the code number for the radio. He bought the car in NYC and lives in Montreal, QC, Canada. We called the dealership, they gave us a code, but it does not fonction. The BMW dealership in Montreal wants him to go there in person for the code. Is there anyway you could provide it? Taking a chance here. Thanks bunches and have a great evening, Summer

The correct radio SERIAL NUMBER is required for a code

First remove the radio from the dashboard.

Then post the radio make+model plus all the letters+numbers on any labels,barcodes and a 14 character Serial Number stamped in the metal casing.

This information can then be used to see if a code can be calculated

Possible failed up stream Oxygen sensor.

You need to pull radio or have BMW pull radio and get serial # off radio, then BMW will run serial # to get security code for you.

With an OHM meter to check the resistance

You need to check primary and secondary resistences, not just primary as you did.
Primary = 0.67 - 1.05 ohms (You may have a bad multi meter if all read the same)
Secondary = 9.3k - 16k ohms Contributing Member

Call around the Salvage Yards or on E Bay for a better price then the dealer. Good luck and hope this helps. 

If the radio is displaying code wait, or wait, then the ignition and radio must remain on for 1hour. I would contact a dealer within the USA and provide them with your radio serial number. The serial number can be displayed in the radio by pressing and holding down the "M" button while turning on the ignition.

on mine where the emergency tool kit is there is the radio code for that vehicle. good luck

Call the dealer they can provide the code to unlock the radio/nav system, tell your dad hands off from now on.

Yes. If it was bought in the US, it was coded for the US, so have a US dealer provide the code.

It will be with your owners documentation packet that includes the operating manual on a card in the radio guide booklet ( I just leave one in the glove compartment. The bimmer comes with two plastic cards displaying the radio unlock code for your radio. If you don't have or can't find the code in the radio booklet/packet, then you can get the code with your VIN (vehicle identification number) through a BMW dealership or a BMW Technician with access to the list. There are even Members of BMW forums that will provide your code via the VIN, but either way this will only work for the original radio (hopefully yours hasn't been replaced).
I bought a replacement radio for my 750 and I wrote the code down in several locations and I suggest you do the same when you get yours, as it's no fun guessing at it as you get three tries and have to leave the radio sit without power for over an hour before it will let you enter another code again and there are 1.000 possible codes.
Good luck.
