Programming of the Tomahawk 9010, 9020 and other key fobs is done using a personal password, a button to enter the service mode and standard buttons on the remote control. Depending on the system model, the combination of controls will be different, usually this is the simultaneous pressing of buttons with indicators of an open trunk and a crossed out horn. The binding of additional communicators occurs in a similar way.

Setting up the Tomahawk 9030 alarm remote control

To flash the key fob for the Tomahawk 9030, it is necessary that the ignition key corresponds to the “Off” position. To enter the service mode of the alarm system, you need to press the OVERRIDE button seven times. The car owner must know where it is located if he programs the remote control himself.

Then the ignition key must be turned to the “On” position, after which seven siren signals should sound. The system can now be reprogrammed.

On the key fob, which is to be linked to the control unit, you must simultaneously press the buttons marked “open trunk” and “crossed out speaker”, as stated in the operating instructions. The keys must be pressed and released after the sound signal sounds. The system will confirm the binding of the new device with CHIRPs (for the 1st key fob 1 beep, for the 2nd - 2, etc.).

The system will automatically exit service mode within 6 seconds after the last action performed.

Possible problems and their solutions

Most often, the communicator is not recognized by the alarm control unit, which is why the user cannot control the security mode and other functions. It is recommended to ensure that the battery installed in the device is in good condition. If the battery is worn out, it must be replaced taking into account the polarity.

Then the following steps are performed:

1. The key fob is re-programmed taking into account the nuances specified in the technical documentation. To do this, it is recommended to study the service manual in advance.
2. If the steps indicated in the manual did not help, you can try to reflash the device using the methods described.
3. Provided that the communicator is intact and the battery in it is working, you need to test all the components of the alarm. The system may not receive pulses due to mechanical problems. You need to make sure that the control unit and other components have good contact with the on-board network. If possible, all wires should be tested using a multimeter, and damaged electrical circuits should be replaced with new ones.
4. The contacts on the microprocessor module, as well as the transceiver, are checked. The connector could be oxidized or clogged, so to eliminate the problem, clean it. If the contact elements are damaged, they must be resoldered.
5. The transceiver location is being checked. Often the lack of signals is due to its incorrect installation. If metal products or body parts are located within 5 cm of the antenna module, this will reduce the range of the key fob. In such cases, the transceiver must be reinstalled.
6. If all components are intact, then the cause of the breakdown may be a software malfunction of the microprocessor. To fix the problem, you may need to reflash the device. It is also recommended to check its board for integrity and absence of traces of moisture. If the unit has been exposed to condensation, the circuit must be removed from the microprocessor and dried.
