you should now have the EWS unit out of the car this is all you need: here is the plug so you can see how that works: The is a black plug on one side of the unit you need to push down on the tab and it should slide out. Once both bolts are undone the unit should just hang down. it is held in by 2 plastic 10mm nuts on a clever but very fiddly to get at bracket. This is what we need to take out of the car. If you stick your head up inside there you should see a white box this is your EWS or immobilizer unit for the car: Once undone the trim panel should pull down. What you need to do is remove 2 screws (possibly 3) mine might have been missing 1 so check all along the trim: This is located here under the steering wheel of the car behind all the plastic trim: Step 1: Remove the EWS Module (or immobilizer module from the car) Key cut (for the lock of car) – Local key smith £6ish.Key case (new)- Again eBay was my friend from here £3.20 delivered.New unprogrammed key internals + chip (the chip is important)- I got from eBay from here (£20 delivered – took 1 and half weeks).I did hours of reading about it from all across the internet and now i have located the correct method for achieving a key and much cheaper.īeing a software developer/ general techie by trade i was not put off by the challenge! Not immediately needing one and slightly knocked back i declined and was back to square one. So when i first got my E46 325 convertible it came with 1 key (diamond shape) this worried me, i asked dealer local to me who sniggered and said it would be a “£150 custom order from Germany” to get another one.
