I have a tec-tus 1 immobilizer, mounted later in my Landcruiser in Germany, possibly from the last century.

It has a sensor with a red LED. It reads ordinary RFID-fobs; I have actually tried putting the cat with its ID-chip-implant to the sensor, and it reads something is there. However, for practical reason I have not added the cat to the known fobs ;-)

I now need to add another fob, but I have lost the manual, and forgotten how.

  • Do they still exist? Do they have a website? Tech support?

  • I've mailed, and got an out-of-office autoreply "I'm out of office until Wednesday 2018" ;-) Perhaps somebody here could answer faster.

1 Answer 1


It turned out the alarm was not made by tec-tus, only the transponder.

I emailed the right company, and got a reply rather early in the morning with pdf's with schematic and programming.

Basicly the procedure is:

  1. Close doors.
  2. Ignition on, then off
  3. Touch transponder with red master fob (for about 3 sec) until led flashes quickly.
  4. Remove fob for about 1-2 sec
  5. Touch again. Led goes solid, then flashes quickly again
  6. (If you want to delete existing fobs, touch with a known fob. Light goes solid, then flashes quickly again)
  7. For each fob, touch until light goes steady for 1 sec and flashes again.
  8. Ignition on and off ends programming.

The german manual is here

  • Thank you for taking the time to write out your answer, and for providing us with the procedure and the link to the manual!
