Hi,

I having this stupid problem with my 3 months old Persona.

Once a week I will facing the starter problem.
When I trying to turn my key to start the engine it just won't go fire... after 2-3 times I need to turn my key back to take out my key and start again...(then it work for this time)

It happen at morning, evening or even night time...


Is this minor? any persona owner facing this problem too ?

Not limited to persona only, saga blm same thing. "Special" feature of proton.

Claim warranty.

Maybe the temperature is low thats why need start a few times ? Try starting your car during afternoon under the hot sun

our persona key come with the immbolizer thing..

try swap to another key and test it.


recommend to use the 2 key alternatively. instead of use dead 1 only...

Oh... so I need to switch the key one a month?

And it happen even under the hot sun.. <.<

sori for ur prob, but mine dun hav any of tht prob..

sept 2007 batch, non iafm

Mine dont have this problem, sometimes the keyslot jam when i turn the key but not a serious problem.

Its very prominent in iafm batch. Its not unable to start, its just harder to start thats all, just crank the engine longer. I suspect the lousy battery that proton supply. I had that problem too, changed to better battery and now not so much of a problem in starting.

mine is 70k mileage now, 2 years n few months already, n still using the mf battery tht they gav it to me whn i bought the car..

n still going strong till today, lucky me i guess..

can a persona driver verify again if Persona has immbolizer
because the last i checked, when test driving the car, nothing of that such.

immobilizer -> send encoded signals to ECU so without a match engine will refuse to start even if starter motor cranks

immobilizer is NOT engine cut off by wire

Persona Lamae ? ada/tak ada
Persona IAFM? ada/tak ada
Persona CPS? ada/tak ada

Confirm got im drivin a M line IAFM model. the encoder is housed in your key itself, next time when replacing the battery for your remote take note of a small black rectangular thing try removing it and start your car.

i own a m-line persona iafm which already 1 year 1 month old, so far didnt face that kind of problem before. Still under the ori battery also.
