ECU rewrite with OBDII paperclip - missing master key solution ???

[Stuey2uk]

<still> Trying to find a replacement master key solution.
Found these...
Short OBD with a paperclip from pin 4 to pin 13 - insert key and leave ignition on for 30mins - 'hey presto' ECU now recognises key ??!!!

Could it be 'this easy' ?- < help >

I'd be amazed but you never know.
A lot of these type of YouTube videos are click bait.

I'm worried I might mess up my 'only key'

Alternative seems to be solder in a new eeprom chip

<pass the magnifying glass >

'Key folk' in this area are busy fixing expensive cars / understandable but frustrating.

Similar to what Scotte said, id be very suprised if it works. But worth a try i suppose if you're out of ideas

Long as nothing broke you've lost nothing and gained knowledge.

So much rubbish on YouTube.
