Peugeot 207 key fob not working

[Keyblade]

Hi DK members,

I have problem with Peugeot 207, after battery change key fob not working any more....
Tried few re-sync manuals from net but neither one work. (turn key to on, press lock button for 20 sec,turn off-take out key. repeat again for 5 sec, take out of the car lock car with key then open car with button- dont work) second manual also...

Can you help me with right sync manual for 207?

Thanks in advance

the corect resynch for 207 , is

ignition on with remote key you wish to program
press and hold down the lock button for 5 seconds
release lock button , switch ignition off and remove key

remote should now be working.

did you check remote before you changed battery to confirm if working or not

Yes ichecked for signal on my KD900 (after battery change) but neither one sync dont work, even yours. key worked before battery change.. Maybe BSI reset or something else?

[rapidlocksmiths]

did you check transponder in the key ?

it wouldnt be first time ive seen it when someone has bodged the key when the antenna on the key fails and car cant see key , they clone from another key a clone chip and insert it in the remote or remove chip from the manual spare and insert it in the remote , remote will only continue working till it needs a resynch .

also ive seen when a remote antenna fails , cowboys remove the chip from the manual spare and attach it to ignition next to ariel ring so any key starts engine , again remote will only work till it needs resynch as the chip being read is not the one that matches the remote .

cowboy jobs like this are far more common now we have the prce cutters and the facebook brigade pretending to be auto locksmiths

did you actually see the remote working before you changed battery or are you taking customers word for it ?

Yes i tried remote by myself before battery change, it worked from outside of the car, "reserve key without remote was in the barrel" after battery change remote dont work. car starts but remote dont work.
This is the first time a had such problem...

id be checking inside the remote case to see if seperate transponder rather than intergrated transponder if a seperate transponder then remote will never resynch , id also read key in a cloner to see if i can read the correct chip in the key as if not there may be a chip taped to ignition.

then check fuses

[rapidlocksmiths]

do not rush to do a battery reset , get this wrong and you could end up with a non running car and a new bsi needed .

if you do attempt battery reset

1) open door , no keys in ignition , pop bonnet and shut door
2) lift bonnet do not open a door or touch anything
3) wait 4 minutes before disconecting battery

these bsi are like an old windows system , they take time to shut down once woken up , if you disconnect battery before the bsi has shut down fully you will kill it .

when you turn the key in the ignition to position 2 , does the info screen say economy mode ?

Dont know, will check tomorrow when customer come back...

Yes #rapidlocksmiths you are right, now i remember it, i see non original chip on key board, they changed the chip on board and transfer to non remote key, Thats why remote worked when non remote key was in a barrel.
After i changed the battery i removed non remote key and tried to re-sync the remote and it failed.....

will check tomorrow this teory....

[rapidlocksmiths]

worth checking , as when in economy mode it can cut off the remote central locking , when battery voltage drops below a certain point the car shuts down non essential functions to preserve power , one of these is central locking.

Am I the only one who dont understand anything from this?

[rapidlocksmiths]

i didnt understand this either ,

saw non original chip on board ? are you saying seperate chip stuck on board ?

they cant have transfered the chip from the remote key to the manual key , as the chip on the remote key is intergrated , ie it is part of the circuit board , soldered to the remote board with an antenna as well , when antenna breaks the car cannot see key , so non start , the cowboys clone a chip from the manual key and stick it to the board or in the remote case .

the remote will not work when the ignition is on at all

Peugeot 207 Ahh !, discussing about its remote key, to ensure that all are in the same track to the right key, rectangular or hart-shaped key. just my two cents.

Its old one, rectangular 0523 remote.

My mistake about not original chip on remote board, i mean it not original antenna on this key board. maybe that's why i cannot re-sync this key (bad antenna)
