Key Replacment

Where is the best place to get a new Key for my X5, and can I upgrade the keys to newer ones or will they not work ?

All E53 has the same diamond style key. Key need to be coded to the car. Best bet is the dealer.
I bought a new one for $185. They will code it for you. It's easy so you can DIY too.

Having an understanding of EWS, FZV, and DWA will help. Unless you want to send your DME or EWS control module off to a vendor (in Canada) or can find someone with an AK90 machine...you'll need to get your key from a dealer due to EWS.

The FZV/DWA (remote keyless entry system/anti-theft alarm siren system) features of the key can easily be programmed by the instructions that get posted on BMW forums at least 3 times a month (sometimes every week). The EWS feature of the key is specific to every BMW...and you won't be able to start the vehicle if the ISN (individual serial number) that was assigned to your BMW as it rolled off the assembly line isn't coded to the the transponder inside the key.

The only thing the keys on eBay can do is be programmed to FZV/DWA...to lock/unlock & arm/disarm..they won't be able to start your car without aftermarket equipment that can used to retrieve the ISN burnt to the DME/EWS control module, then write that number to a new EEPROM transponder.

And with the new style key...you'll also need to find a way to keep the internal battery charged. The new style (diamond shaped)key like the e53 uses...is charged when the key is in the ignition. So if the key isn't cut to slide into the ignition and turn to at least position 1 or 2...the battery will eventually die...and the FZV/DWA features require power from the internal battery.

If you don't need a "remote" key...BMW sells a non remote key that is a lot less expensive than the remote keys. It just has the single EWS transponder inside...but not the FZV/DWA features (you manually insert the key into the lock cylinders..the old fashioned way).

And I don't remember anyone answering your question about the new style keys yet...the answer is no (without some type of electronic wizard). The new CAS (car access system) keyless entry system is designed for the new generation BMWs. They have a totally different communication bus (CAS-bus)...whereas the E53 X5 uses the I-Bus/K-bus/P-bus system for its EWS 3/FZV/DWA:

(the e53 uses K-Bus/P-bus/I-bus protocols for communication)




(newer CAS BUS & EWS 4 used on the new generation BMWs)
