How can I disable my Immobilizer?

I’ve gone and put my key through the wash, about a week ago, and my key worked fine until now. The chip isn’t working therefore disallowing me to start my car.

I was wondering if there was a way to bypass/remove my immobilizer, so I do not have to buy a $500 chip for my key. Removal of the immobilizer would be ideal, as then I would be able to use an after market key instead of a genuine one.

Can anyone help me out?

Are you sure you even have a chip in that key? BMW didn’t start installling those chips until 1/95. What is the production date of your car?

I had a production date of 10/94 on my old 325 and it did not have a chip.

I have a chip, for certain. I’m holding it in my hand.

My car is, 04/95. I just need to be able to cancel the immobilizer somehow, or start the car an alternative way?

on gm cars you can put a resistor in line but i doubt that will work on these. you likely need a new key. even immobolizer bypass modules require a second key for these cars.

Well you are in luck then. Your DME is a silver label 413. You need a Red label 413. They are the same except the silver label has EWSII installed and requires a chip in the key. There is one or two other steps you need to do to accomplish this but I can’t remember exactly what they are. Its pretty well documented if you search for EWS delete or 413 ews delete or something similar. I believe it involves cutting one or two wires.

In the US you can pick up a red label 413 for about $75-100. They were used in all 93-95 325’s. Coupes, Verts or Sedans (saloons). As long as its an M50 engine with Vanos and its before 1/95 production it will have a red label 413. You’ll even be able to use your existing key.

I would suggest one or two things though. If you don’t have a spare key you really need to have one. Ive never heard of a replacement key for an e36 costing more than $125 US. Even from the dealer. If you accomplish the EWS delete you can get a blank non-chipped key and have it cut to match your ignition. That shouldn’t cost more than $50. Either way you are looking at spending $100-150 to accomplish what you need.

Hope that helps.

Thank you mate! That was the most helpful post I could ask for, I’ll have a look over this and see how I go!
