BMW Car Key History

Since BMW launched their production line until around 1995 the car keys they used were 100% mechanical. So basically, if someone got the lock to turn there would be no other layer of security to protect the door from opening, the ignition from starting and the car from being clear for driving.  That wouldn’t offer much security to the car owner because ‘the bad guys’ could easily use a pick-set to pick open the locks and steal the car. Being professional locksmiths, we know well how to pick locks to help our clients gain control over their vehicles. Thus, believe us when we say that the vehicles using mechanical car keys don’t offer much challenge to the common car thief. To add to that, stealing a car with mechanical key could be a very quiet process for that matter.

 At the late 80’s and the beginning of the 90’s BMW introduced a new key offering a new security level that was called ‘High-security 4-Track external’ (HU58 or S7BW). The high security measures involve producing a key blank that uses different and yet another dimension engraving patterns that make the locks a lot more sophisticated and much harder to pick-open and service as compared to the ones designed for the older car keys.  

 Around 1995 BMW introduced a transponder system for the keys called EWS (Elektronische Wegfahr Sperrethat is also used by Range Rover, Land Rover Mini Cooper and more.

At the beginning the EWS (1 and 2) systems used the HU58 key-way and later around the beginning of the new millennium BMW changed the key to a simpler version of high-security key that had ‘only’ 2 tracks (HU92) instead of 4. This new key was integrated with EWS3 EWS4 and EWS4+, which means that it was more sophisticated and harder to remanufacture.

It goes without saying that Multi-Locksmith BMW car key services involve making and programming all types of EWS keys right on thespot in the field as a part of our mobile service and it typically takes 1-2 hours of work.

You are probably asking yourself why choose the simpler version of the key? Well, at that time there was a peak in using electronic security devices (transponder/EWS), so, practically, it was very hard to steal a car. You see, a simple turn of the key could not start the engine, there were more layers of security added to the mechanical car key and therefore the key could have been downgraded to a simpler key that is easier and cheaper to manufacture.

Around 2005 the EWS transponder system no longer met the expectations of BMW engineering team so they started another system to replace it and called it: ‘CAS’ (Car Access System).  As you’ve probably guesses there are CAS1, CAS2, CAS3, CAS3+ and CAS4 versions of ’CAS’ systems. 

For the first few years the CAS system used a ceramic transponder chip inside the key just like the EWS transponder chip. Later on, the car manufacturers started using a push button in order to start the car (PUSH TO START/PTS from 2005 onward) and this was the end of the mechanical ignition and the mechanical keys that started the car.

Bimmers with ‘PTS’ use CAS2 systems and higher (except for BMW 7series 2002-2008 that comes with PTS with CAS1 or 2 system).

As we’ve mentioned above no BMW ever has keyed ignition, the only mechanical key that is still in use is the one designed to open the door in a dead battery situation or to lock the trunk manually. This key is called E.key (Emergency key) and it is usually slide in to the prox remote.  

The BMW mobile locksmith service of Multi Locksmith includes making and programming BMW keys and prox (PTS) up to CAS4 (2010~).

In addition to the EWS system all of the mechanical BMW car keys have another component within the fob remote control. It is essential to know that Multi Locksmith can make remotes and fobs for most of those cars just as well.
