3 Using a good quality desoldering station carefully
remove the eeprom from the remote circuit board by
applying hot air directly onto the soldered legs of the
Eeprom. Hold the Eeprom with tweezers and allow gravity to
drop the circuit board from the Eeprom. Now using the soldering iron on the soldering station
and desoldering braid carefully clean and remove the
excess solder from the pads on the remote board. This
prepares the surface so that when the Eeprom is soldered
back the electrical connection is strong.

Use solder to tack the virgin PCF7946 in place then
starting on the other side re attach the legs to the
remote board using the soldering iron. Use an eye
piece or magnifying glass to ensure all legs are soldered
and not shorted out.

Once the soldering is complete and a new PCF7946A
Eeprom has been soldered onto the circuit board place
the remote circuit board into the transponder writing slot
and select “recycling” on the Zedfull screen, in the sub menu
select “refreshing remote”.

Next select Renault PCF7946, then follow the on screen
prompts and select refresh.
Once the process is successful you can read the
transponder in the Zedfull, the mode will be displayed
as Cipher-Manchester. The remote is now ready to be
programmed into a different vehicle i.e. Renault Clio 2, Kangoo
2 , Master 2, Traffic 2, Vauxhall Vivaro and Movano. All these
vehicle use an ID46 Transponder which is on the remote
board so the remote programmes automatically with the
transponder.
With a new remote costing £50 - £60, the option to refresh a
remote can be achieved for as little as £15 therefore leaving up
to £35 - £40 profit.
