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

[rapidlocksmiths]

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

[Keyblade]

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 ?

[Keyblade]

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...

[rapidlocksmiths]

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 ?

Will check for this. Thanks again

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....:uncomfortableness:

[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.

please read post #9 i edited post....

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)

My mistake, i mean it not original antenna on board. Maybe signal is weak or something, i got signal on KD900 but...?

The rectangular is new one ! The 207 with hart-shaped-keys are on early 207 cars which may not seem common in some market I think !

Remote key work before changing battery, after didn't. So the problem is between.

I've never need resync this rectangle remote just after changing bettery. Even after full repair the PCB , rarely need resync.

So the problem is during your changing battery, you dammaged the remote.

[rapidlocksmiths]

yes the issue is either the remote is damaged during battery change , though you have to go some to break these or a less obvious issue as detailed earlier in thread , also coincidental faults occur .

as stated check for non original transponder chip stuck to board or seperate in case .

does the key read in cloner as correct chip ?

does the remote give the correct 433/434 mhz signal ?

FYI the antenna on the key is for the transponder to start engine and not for the remote control part , the crucial thing is that the transponder and the remote are a correct married pair , if not the key cannot resynch .

you need to check , once you have ruled out these issues , then as working when you changed battery it will be down to you to fix or replace , even on coincidental faults , we all get these , but if working when it came to you then it needs to go back working , this is why i asked if you had tested it fully , as customers often have you over in an attempt to save money .

check battery voltage on car and ensure not in economy mode , apply support if required , also check the battery you fitted as wont be the first new battery to be low voltage

since the emergence of so many messers doing car keys with no experience and no idea about keys and immobiliser systems , ongoing issues are getting more common , with so many cloning rather than coding proper keys , many are getting caught when clone key wont go back into system when new keys needed , on psa some are getting caught out with clone chips in keys when antenna fails , and im seeing far more chips taped to ignition , this is the legacy of the price cutters and those pretending to be auto locksmiths , and a new cross we must bear and work around.

I checked the signal with KD900 after battery change and remote work ( got frequency 434 and ASK modulation info )

Remote chip also start the car i tried it and car starts, but i cannot resync remotes to work again.

[rapidlocksmiths]

so you checked signal after battery change , and key starts the car , remote should have continued working then without resynch being needed.

again check board and case to confirm intergrated chip and not a bodged seperate clone chip .

read the key in your cloner to confirm correct chip can be seen , if no chip can be seen by cloner and key still starts car then possibly chip taped to ign.

check battery voltage on car and check battery you fitted is good too and car is not in economy mode.

check fuses , does internal central locking button work ?

you can try battery reset if following the 4 minute rule

if no joy and key was working prior to battery change then take it on chin and replace key

[rapidlocksmiths]

why did the customer bring the remote key to you for battery change ? most dont till remote stops working altogether , so if remote working as it should be then what made them decide to change the battery ? or was there a problem wit the remote working intermitently or not properly , so they self diagnosed the battery ?

He bring remote to change broken key fob,when i changed key fob i changed also battery..

[rapidlocksmiths]

change fob ? do you mean a recase , you fitted a new case to existing remote board and battery ? or you changed remote fob ?

i will assume you recased existing remote fob/board , so you changed casing and battery , did you check condition of micro switches , battery connections and verify intergrated chip and not a seperate transponder stuck on board ?

in that case then if voltage in your key battery and voltage on car are all good , car not in economy mode and internal central locking button is working still , then its possible you have damaged board somehow during case change so need to replace the key , use kd NB remote 0536 ask , as if a car issue you can at least reuse the key on another car if still fails .

if unsure whether chip on board is wrong post a picture of the board

[godfathertwo]

I check each battery with a voltmeter and ask questions first I have been to job where customer changed battery and damaged board also to lots where they fitted battery upside down
They go in you tube than think
They can program keys or Remotes
Themselfs so and they always lie and always ask is anybody tampered with car or remote or flat battery.

[Keyblade]

#rapidlocksmiths you were right from the beginning, previous locksmith glued chip near the barrel lock, he was lazy to put chip in reserve key case.
I removed the chip and programed key in 5 seconds, then moved this chip to reserve key case and glued it inside....

All the trouble because of laziness.

Thanks again rapilocksmiths...

[rapidlocksmiths]

you will see much more of this due to the amount of facebook experts and bodegers doing car keys with no system or trade knowledge , all in a bid to drive the rates down .

as more and more people clone keys rather than properly code keys you will encounter more and more issues in future , for them to earn enough for a packet of cigarettes on a job , it will cost you more than they earnt to put there mess right .
