Hi

i've got a customer with a 2003 Freelander wanting me to quote him for a new key. I've not done 1 for a Freelander before so i'm not sure where the immob module is. With is being a 2003 it could either be the BMW EWS system or the SAWDOC system.

I've done a few L322 keys & the EWS is in the center console whereas with BMW & Mini the EWS module is behind the trim above the throttle pedal fixed to the bulkhead

So does anybody know where the EWS/SAWDOC module is on a Freelander? if the customer was local i'd just go have a look myself but he's 30+ miles away

I was under the impression both Hawkeye and Autologic reprogrammed fob by using the odb port.

Is there another way ?
 
Immobiliser/keys/fobs are programmed via the odbii port if you have the correct kit to do it.
 
new keys aren't programmed to the immob via OBD with any equipment I have. It's all eeprom work. I can order a genuine Freelander key to chassis number from my key suppliers & it will come already cut & programmed direct from the dealers.

With the BMW EWS system there's 4 key id's stored in the immob module. 2 are supplied new with the car. If your order a new key from them they generate a new key with the key data for example for key number 3 in that's stored in the system & in the module. So when you pick it up from the dealers & put it in the ignition the immob module recognises it as key number 3 so it will start straight away.

SAWDOC keys also come already cut & programmed.

When i do the EWS system keys i have to remove the module from the car, read the eeprom data then make a new transponder with info read from the eeprom data. This alters the original eeprom file as it generates the new key into key position 5 so i then write the new modified EWS eeprom file to the EWS module then fit it back in the car.

This is exactly the same for BMW, Range/Land Rover, Rover 75 & Mini's using EWS system. The newer models use a CAS system which is a similar process but with different equipment.

As for the Freelander remote side of things. I have an OBD programmer that will program Freelander remotes but again as i've already said it doesn't program the transponder chip to the immob via OBD.

I've never looked into equipment for programming Freelander transponder keys via OBD because i've never been asked to do a Freelander transponder key before. I've only ever done the separate 2 button remote fobs which is programmed with the same machine that does most other makes of key
 
That may well be the case. Rave covers it in detail, but not everything due to the nature of the subject. My hawkeye can add fobs from another vehicle to my hippo. It also shows 10 slots available for keys and will allow you to enable or disable them. I've played with this and it will also give feedback on which key number is being used and if it's valid, elsewhere in the menu's. Both keys used to do this previously worked with my hippo anyway.

Test Book (T4) programs everything through the odbii socket. LR main dealers use it.

Be careful when reprogramming as you can easily knock out the synchronisation (mismatch error P1672) between the engine computer and the immobiliser computer if things go wrong. Best to make sure the hippo is located in a position to easily allow a recovery truck to carry it to a main dealer if it goes wrong.

Few people will know the exact key magic required as those who have asked in the past have normally used garages who have done the work in the past on other hippo's so they haven't had any problems. So our knowledge is limited. Immobiliser is located left of the steering column behind the dash, on all Freelander 1's from what I've seen.
 
ok thanks for that! i've done 100+ keys to vehicles with EWS system & not had a single problem with data mismatch yet.

I always save the original EWS eeprom file & have even got a couple of EWS modules in the garage for just in case anything did go wrong

Ah! That make sense now, you are saying the immobolizer works with the part with the key itself, the little piece in the key "head" Remote fob plip programming has nothing to do with "starting the card" but only unlocking the doors!

WOW thanks for that detail.!

Everything I see under the hood is in "pastic containers" I have no ideas where those modules would be or if they are inside the cab instead.

Hippo, do you have a picture so I can compare with a NAS version of freelander to confirm it if it left or right at the front? Things tend to move with the North American Version.

yes, this is the case with most car keys. On some models, not many though the remote disables the immob. Such as some Rover cars & 2000-05 Disco. They don't have any form of chip(transponder) in the actual key. A lot of people seem to think that a transponder is a remote, which it isn't. A transponder is a small chip coded to the immob

The modules are in the cabin. Usually behind the dash trim or as with L322 RR's behind under the center console trim
