Removing NEC chip on Mercedes keys for beginners

[@tomking3942]

I watched this just for the soldering tip. I was having trouble with these small chips with lots of legs. Nice tutorial.

[@oltianmunga9921]

hi guys this method is really for beginners but this method is also difficult for pros so its better to use hot air soldering gun to remove the nec processor and if a key can't be repaired just take the nec processor and solder it to a new key board and it will function and start the car also control remote locking and opening doors without the need to reautorize the key to the car with diagnostic tools, i do this on daily basis. great video keep it up guys.

i just done it swap to other mb key board (wich looks the same) but on my one hav ir led big and small and new one hav 2big ir leds one on front and 1at back of board. nothing is working on that - after button pressed red led lighta up for couple of seconds. also ir for immo not blinking fast but lights up contuniously for couple of sec. what done wrong? my car sprinter 2007 key is form c class dont know year looks same from outside...

[@MrAluislugo]

Where do you get a new key board please?

[@killacam1jz]

Hi, so I swapped my chip but it doesn't open or start the car anymore. Remote light flashes after I press a button. What did I do wrong?

[@cassk9999]

@@kryspla wrong key obviously two different frequencies or nec chip not soldered on correctly to broad

[@5905-k8v]

Is the resetting of the used key called flashing ???

[@dashtyATG]

Thanks for your time

[@moeenhamza3468]

nice work for benz key programming thank you

[@agoodneighborautorepair2176]

Very nice explanation and information.

[@1974charrua]

Thats good mate , you can also read/write on the nec prossesor without de-soldering it .

[@killacam1jz]

Can I transfer my nec chip into a brand new key and it just works?

[@techgeek2994]

what if you solder like that 2 legs together by mistake it wont work ?

[@DVLZHAZE]

does anyone know if your board is damaged can you swap the NEC chip onto another board? will it start the car? does any other chip have to be swapped for it to work properly?

[@m.s.maksoedan720]

If the NEC is ok then swapping to a working board will do the job.

[@stein-arnefalchpedersen2222]

Great video. Much appreciated!

[@yasoutherncousin]

How much does this service cost?

[@MyTho.1]

Did you get pin 1 lined up?

[@prattandwithny]

nice job

[@5905-k8v]

Is the restting of the chip called flashing the chip ?

[@mostacardiagnostic2913]

Hello if you can delete and write nec f9234

[@MistaChubbz.]

Can you use a used circuit board from a close to new key fob to do the swap?

[@karned273]

Yes, you can do it. Only NEC swap

[@DVLZHAZE]

@@karned273 with just a NEC swap will you get all the button functions as well.

Merci

It is very funny for a beginner to rework on a mercedes remote key that costs a few hundred dollars.A 555 timer project is always a good starting point for exercise.

[@nkhan7804]

Hi sir I have my original key and new I need to clone the new can u doit?

[@MistaChubbz.]

N Khan same question!?

[@dj1encore]

same question

[@karned273]

No guys, You cannot clone this chip. U have to write new key (chip) to EIS.

[@DVLZHAZE]

@@karned273 so what's going on in the video. is he erasing the chip then reinstalling it as if it were a brand new key and somehow they sync?

[@karned273]

@@DVLZHAZE I think he is just resetting the chip. Now You can program this key in another car

güzel video :) can you help me to read nec d78f0515a mcu

franchement je suis pas conprande mes guaa

[@diagauto4689]

Great ,but you have token a long time

[@les536]

That's no good how your doing that I have been a electronics technician for 25 years and that NEC integrated circuit can be destroyed by electro static discharge from your body not once did I see you ground yourself with a wrist strap..I only point this out because it be a shame to take the chip out just to destroy it

[@eazzyfizzle3971]

you are also correct but this works this way, ive done it 1000 times same way and never did the nec break

[@frankensteinke]

What would be the use of a wrist strap? What would you ground to?

[@les536]

The point of the wrist strap is to dissipate the electrostatic charge from your body so that charge does not destroy the low voltage sensitive components threw the conductive legs of the NEC program integrated circuit

[@HardwareHQ]

If using tweezers best to use ESD tweezers with Electrostatic discharge (ESD) specifications
