Can anyone helps please.....

Thanks in advance !!

Hi,

When you change the battery , mayby you lost transponder .Check if you have the transponder in key .(ceramic or Glass).If you have integreted transponder on chip , check contatcs and resolder inductor .

I hope this will help.

chip is in inside on both keys....i think the prob is in immo box(if it has ) or at the dash.....
if someone has same prob maybe knows
thanks for help any way ...

Program both keys again ad car will start

I think is immo2!Reprogram key!

I try to reprogramm but none of my machines MVP or SBB can connect ......i cant connect...this is my prob ....!!

I have similar problem and is the immo box that dont feed the reader coil in key cilinder.

[keymaker.gr]

Did you found solution ??

Changing battery has nothing to do with starting engine. The car must start even without remote (separated transponder) and battery, only by mechanical key and transponder (probably glass ID13) near ignition coil. If other key works then you lost or damaged transponder. I would not touch the car electronics before I'm sure in that.

Edit: Now I see, misunderstood, tought on changing remote battery not car battery

read above please !

go to this post and make a coil tester to check if the immo antenna coil is working,

also if both your units SBB and MVP do not connect there sre two possibilities, if they both power up then the system has blocked and you need to find a reset procedure. if they do not power up then it is eobdii power supply problem, change fuse or use external power supply.
i seriously suggest that you make the coil tester it saves alot of time waisting when you can rule out things as easly as this.

Thanks for the help.....i have power ....but they just cant connect ...cant find ecu.....

I made the test and immo antenna is not trasmitting.....do i have to change antenna or there is a prob inside ecu ??
Does anyone can help with any info for any solution please ??

First scan modules for communication, my case was a problem in immo inside cluster, it communicates but didnt feed a reader coil, you must read parameters and codes in Instrument or Instrument insert, if cluster dont comunicate try comm with ECM, ABS, SRS, TCM. to see which code are present, very important if in engine codes you have "engine blocked by immobilizer" , if all have data but cluster not, check board for losses solders, make me informed..

do the simple things first, check the wiring, check the connectors, use a meter to see if electricity is going to the antenna, if no power is going to antenna then it is immo problem if power is going to antenna then problem is burnt coil in antenna. allways try to keep your testing procedures as simple as possible. do not assume ecu or immo without checking the basic things first.

also use the coil tester you made on a car that is ok to check if you have made the tester properly in the first place.

the test with coil is ok...i'll try if power is going to antenna next step....
Thanks for help both !!
