Question about E34 Keys

[oldskoollove]

greetings all,

so this weekend i will become the proud owner of a 1989 bmw 535i, 5spd. . .i spent all this week reading up on the e34 and starting out as at least a somewhat educated owner. i've been amusing myself by looking on e-bay for random e34 offerings and came across an uncut e36 key (the keys that i will inheret are a rag tag bunch). the seller advertised that he thinks they MIGHT fit an e34, i'm not trying to take his word. but that brought up a question about parts from/for other bmw models that may fit the e34. so how would i verify this key possibility and for the future where should i look to figure out if something may or may not fit the car.

thanks in advance for your advice.

Make sure it look exactly like your key.

Do you have the side winder style?

i'm don't rememeber the keys exactly, but i believe they resembled yours as well as one that had the red light in the key fobe. . .but i am curious if i can go with something like the one being listed on ebay which is so much nicer.

Just make sure that if you have the Huff side winder style with the flat tip & rear notch, you get that blank.

You will also have to find a lock shop that can cut it.
Mine charged $35.00

huff side winder? i think i understand the flat tip and rear notch reference. i'm assuming that the key that you showed me wouldn't have been one?

Once it is cut, it will have all four sides grooved with the spine remaining like a blade. (original blank profile)

BMW online parts database: http://www.realoem.com/bmw

...save it to your favorites folder (bookmark it)...its an invaluable site for part numbers, wholesale part prices, diagrams that illustrate how stuff goes together, part info (like wheel offset, width, height).

For example...the e34 used different keys during its production run depending on model. The V8s (530i/540i) used a fat head black key...and the 540i (1994 model year) used a different anti theft system (DWA) instead of EWS II. Also starting in model year 1994...driveway protection feature became standard across several new series incl the e34. Driveway protection safety feature now not only secures the doors etc but now disables the ignition and fuel delivery system when the car has been double locked. So no, the e36 key may not work in your 1989 535i...but you can check and compare it to the availble keys shown in the diagram from the online database (keys #2-#5): http://www.realoem.com/bmw/showparts...44&hg=41&fg=40

Note: only the items that show up in the parts index below the diagram are available for your 1989 535i. The e36 you refered to may use some of the keys from group #21...those keys aren't for the early model e34s. And only the e34 V8s use the keys from group #7 or #18.

You could buy one of the other keys that have the remote transponder/chip embedded within...but you'd be paying for something that you can't use. Even if you purchase a blank one from eBay or the e36 owner...by the time you find someone who can cut the key correctly for you...you'll have probably paid more than just ordering one cut from your car's VIN by your local BMW dealer. Again, check out the link to the key diagram above for your car and order accordingly...don't let them try to sell you one of the more expensive keys...they won't work in your 89.

I ordered a pre-cut key from the dealer and i think it was less than $30 total, so it might pay to check there first instead of spending more at locksmith shop.

You just need to give them your VIN and show them the title to prove you own the car.

Also, the new key from the dealer looked nothing like the cut on the old one I had, but they both work!

One strange thing is that the old key will deadbolt lock/unlock the doors only from the passenger side, and the new key will only do that from the drivers side. Normal locking works the same from both doors, the trunk, and ignition.
