catmand00 Posted September 4, 2015 Share Posted September 4, 2015 Apart from obviously insurance invalidation and disabling the immobiliser are there any car problems if I remove the transponder ring and position it elsewhere with the active key chip taped up to it so I can then use plain cut keys to run the car? Ie would the alarm be disabled too or will the doors not lock by remote as there would technically always be a key in the ignition as far as the cars concerned. I want some spare keys and atm as a temporary fix due to not having £100 for each key I was hoping I could do the above and buy 2 brand new cut flip keys then next month or 2 get these 2 new keys coded it thus having 3 then revert back to original and use keys properly hope this makes sense. I know the transponder ring will need to be moved or it will pick up the chip from the uncoded key too and won't start but any other problems or thoughts please Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted September 4, 2015 Share Posted September 4, 2015 Insurance invalidated. Car won't lock. Alarm won't function. You could steal the car with a rusty spoon. 2 Quote Link to comment Share on other sites More sharing options...
artscot79 Posted September 4, 2015 Share Posted September 4, 2015 A mobile locksmith will take a heck of a lot less to just supply cut and code I would not do the above the alarm I'm sure will not activate as the chip is there all the time really you could nick the car in a heartbeat 1 Quote Link to comment Share on other sites More sharing options...
Dee_82 Posted September 4, 2015 Share Posted September 4, 2015 Modified elm 327 device, 20 quid uncut key, 20 quid. key cutting, 5 quid forscan, free 50 quid for the first 25 there after Pats programming is now available with forscan software 2 Quote Link to comment Share on other sites More sharing options...
catmand00 Posted September 4, 2015 Author Share Posted September 4, 2015 I'm hardly gonna put a sign on the car saying immobiliser bypassed please steal me lol. Everyone knows they have an immobiliser so bypassing it isn't gonna make it suddenly become a theft magnet. I tried it this afternoon and just for the record it locks and sets the alarm with no problems. Not recommended obviously for the reasons as said by everyone above. Will be using forscan this evening to program my 2 new keys in awesome Quote Link to comment Share on other sites More sharing options...
IINexusII Posted September 4, 2015 Share Posted September 4, 2015 i wouldnt mess with it if i were you, like Darren said, forscan now has PATS programming, and i used it myself to program the keys when i changed from the MK2 to MK2.5 instrument cluster 1 Quote Link to comment Share on other sites More sharing options...

catmand00 Posted September 4, 2015 Author Share Posted September 4, 2015 Do the newer style flip keys work? The ones with the large ford logo on the back and the keyring on the bottom as apposed to the corner Quote Link to comment Share on other sites More sharing options...
JW1982 Posted September 4, 2015 Share Posted September 4, 2015 The latest design Ford flip keys that are used on the Focus MK3 (and other Ford models) are not suitable for the Focus MK2/MK2.5. The PATS chip is identical so the newer keys can be programmed to start the engine without any problems. However the remote central locking will not work. Both keyfobs operate at the same frequency but I suspect that the command codes transmitted by the keyfobs are different. Quote Link to comment Share on other sites More sharing options...

Dee_82 Posted September 4, 2015 Share Posted September 4, 2015 You can still get flip keys. This one is a clone, but there are genuine uncut ones around too http://www.ebay.co.uk/itm/Ford-Focus-2004-2010-new-3-button-remote-flip-key-fob-Brand-new-Never-used-/321362311146?hash=item4ad2afb7ea Quote Link to comment Share on other sites More sharing options...
catmand00 Posted September 4, 2015 Author Share Posted September 4, 2015 Thanks Dee_82 I've got one of those but I was hoping the newer type would work as they look better Quote Link to comment Share on other sites More sharing options...
Dee_82 Posted September 5, 2015 Share Posted September 5, 2015 Without see the insides it might be possible to transplant the electronics from the old one in to the case of a new one, just depends on the physical layout of the buttons and the size of the pcb Quote Link to comment Share on other sites More sharing options...
JW1982 Posted September 5, 2015 Share Posted September 5, 2015 The old and the new design flip keys are internally completely different. The old design flip key has a 2-piece design housing. This key has a key part (which contains the PATS chip and the keyblade) and a remote control part (which contains the battery and the remote control circuit board). The new design flip key has a 1-piece design housing. This key has a much larger circuit board which contains both the PATS chip and the remote control circuitry.

Dee_82 Posted September 5, 2015 Share Posted September 5, 2015 but if the two parts can physically fit inside the housing and align with the buttons then with some DIY and a large blob of glue, it might be possible to transplant the 2 old PCBs in to the new housing. i dunno for sure but where there is a will there is a way... unless it physically wont fit in at all. 1 Quote Link to comment Share on other sites More sharing options...
JW1982 Posted September 5, 2015 Share Posted September 5, 2015 The new design flip key officially can not be opened at all. After assembly the housing is glued and opening the housing without damaging it is very difficult. The only part of this key that can be removed is the cover which is needed to change the battery. I have both the old design flip key and the new design flip key (both defective ones) in front of me and the circuit board of the old design flip key will never fit into the new design housing. This will only work if you have the skills to design your own circuit board with the dimensions of the new design flip key and the electronics of the old design flip key.

catmand00 Posted September 5, 2015 Author Share Posted September 5, 2015 So there is no way to have the newer shape key fob on a 2009 focus. Quote Link to comment Share on other sites More sharing options...
JW1982 Posted September 5, 2015 Share Posted September 5, 2015 Everything is possible but in my opinion the amount of work involved to get it working is not worth it. About 10 Years ago as an experiment I converted an Audi flip key to work with my focus MK1. It took me a lot of time and effort but in the end it was fully functional.

Dee_82 Posted September 5, 2015 Share Posted September 5, 2015 pulling out the dremmel to hack the insides apart is one thing, redesigning a PCB is going to be a pure pain in the ar$e given that i suspect its all surface mounted. Meh, there are better things to be getting on with, like JW1982s rear drum to disc conversion :D 1 Quote Link to comment Share on other sites More sharing options...
