Why is my Steelmate 888N transmitter ineffective?

  Brittany MyersAug 6, 2025
  If the Steelmate Car Alarm transmitter is not working well or the control distance has significantly decreased, it could be due to several reasons. First, check if the antenna is installed correctly. If not, reinstall it in the correct location. Also, inspect the wiring of the antenna to the ECU. Tall buildings or electromagnetic waves might interfere with the control range, so try to minimize such interference. If the transmitter battery is low, replace it with a fresh one. You may also need to reset the frequency of the transmitter or replace it if it's broken or damaged.

  If the siren of your Steelmate Car Alarm chirps sharply for 10 seconds after arming and the same happens after disarming and re-arming, the sensor may be damaged, so replace it. Also, ensure that all doors and the trunk are properly closed. Inspect or replace the door's pin switch and check its wiring.
