Disco 2 TD5 disco key fob coding question

I know it has been covered alot but i can seen to find any posts that answer my question .

using my hawkeye i can code new keys with the tags . my question is will the old key that is currently being used still work ? does it also need coding in when coding the new key? will i need the tags for the old key to code it in?

any help will be great ..thanks

Not sure on hawkeye,

But the nanocom gives you a choice of which slot to use for the "new" key fob. So you identify which one is already used and uitlise another one. But this is also with the small chip code not the long tag code.

Does the hawkeye allow gou to identify which key fob slot is being used already?

Cheers

well its been a few years since ive coded a d2 key and i cant remember if it has such options . but on that vehicle the old key was not working so it was not needed then .. now i have a case of an owner needing a spare key just in case anything happens to the original . i dont even have the vehicle here to acces the program in the hawkeye to see what options i have ..

I have hawkeye but i've never used it for fobs cos i'm using nanocom for that, though i'm sure that hawkeye will let you see and choose the slot to save a key code so what i can recommend (not 100% though) is that if you can access with hawkeye and see the slot let's say slot 1 you can identify if the old key is saved there so open the fob and read the short code which is on the circuit board then when you'll see the long code with hawkeye the first 6 characters after the first letter(which might be G for UK) should be similar... so if it's so let that slot alone and save the new key in the next one... for example if the short code on the fob's PCB is 321C36 and saved in slot 1 the long code which you see with hawkeye in slot 1 should be G321C36321C35FFD .... i didnt try this myself but might be correct and then you are settled, let us know if it's so though if this is not this way in slot 1 go through all 4 slots to make sure cos if my theory is wrong then you'll not know where the old fob is saved and might change it with the new then only the new one will work

yes its the last bit there that has me worried . if i mess it up then i will lose the new key fob to the customer and not get paid . . i could arrange to "Try" and code the fob and see what options i have with the hawkeye hooked up to vehicle .
by the way thanks for all the advise so far ..

I've seen few codings myself and the vehicle's 2 original keys were always in slot 1 and 2 so slot 4 should not contain the old fob's code though you never know for sure, i have hopes that you can figure it out as i said if my theory is correct...good luck

Thanks sierrafery you always give the best advice . it may be a few weeks before the vechicle is able to return for further investagation .. i will try to update as soon as i get through .
