This car has what we call a VAT's key security system. the most common problem with this system is that the resistor that is in the key looses it's resistance value and the security system no longer accepts it. as a locksmith I run into this very often and the fix is very simple but needs to be done by a locksmith or a mechanic that knows what they are doing.
the fix requires the teardown of the steering column and fitting ( hard wire ) of a resistor with the correct value directly to the ignition switch itself,, this basically bypasses the key security part of the system and from that point on you will be able to use just a regular ignition key ( flat key NONE VAT's key ) which will save you a lot of money in time when getting copies made, ( regular keys cost about $2.75 -- VAT's keys cost around $29.95 per key ).
seek out a local automotive locksmith or mechanic and tell him what you would like to have done and for about 85 dollars this fix can be done ( the cost of the resistor is about 5 dollars ).
this will solve your problem.

Do you know anything about automotive electronic's ? Control modules ?
Vehicle Security Module
The vehicle security module receives inputs from the following:
  • Door ajar switches
  • Keyless entry keypad
  • Ignition switch
  • Remote keyless entry (RKE) transmitter
The vehicle security module uses these inputs to control an output signal to the instrument cluster which controls the battery saver relay and interior lamp relay. The battery saver relay and the interior lamp relay are internal to the instrument cluster, and are not replaceable. There could be a faulty switch input to the I/C - insturment cluster , causing the vehicle security module to activate the lock's an light's .
Interior Lighting Systems
The instrument cluster grounds the battery saver relay and interior lamp relay coils when any door ajar switch is opened, or the interior lamp (headlamp) switch is closed. The interior lamp relay then supplies voltage to the interior lamp circuit. Vehicle speed must be less than 24 km/h (15 mph) for the instrument cluster to ground the interior lamp relay. The interior lamps remain illuminated for up to 25 seconds after all doors are closed unless the instrument cluster receives an input from any of the following:
  • voltage from the ignition switch.
  • a vehicle speed signal.
  • input from the keyless entry keypad through the vehicle security module.
  • input from the RKE transmitter unlock or panic switch through
  • the vehicle security module.
Do you know what DTC'S - diagnostic trouble codes are ?
Could have DTC'S stored in the following Modules

B1328 Passenger Door Ajar Circuit Open Instrument Cluster Go To Pinpoint Test C . B1342 ECU is Defective Instrument Cluster CLEAR the DTCs. REPEAT the self test. If DTC B1342 is retrieved again, INSTALL a new instrument cluster. REFER to Section 413-01 . All Other DTCs - Instrument Cluster REFER to Section 419-10 .

How do you replace the bulb behnd the cluste on a 1994 Honda Acord, I removed the two top screws and the AC knobs, does the radion and console have to come out as well?

yes, the radio has to come out, as 2 of the trim panel screws are hidden by the radio.

1990-95 Accord
See Figures 7, 8 and 9
  1. Disconnect the negative battery cable. If so equipped, disable the Supplemental Restraint System (SRS).
  2. Lower the steering wheel to its lowest position.
  3. Remove the center console.
  4. Remove the ashtray and ashtray holder.
  5. Remove the radio/tape player.
  1. Remove the coin box, switches and dash light controller from the instrument panel.
  2. Remove the mounting screws securing the instrument panel. This is a large, formed piece of plastic-don't crack it.


Fig. Fig. 8: Instrument panel retaining screw locations on 1994-95 Accords

  1. Lay a protective piece of cloth over the steering wheel pad.
  2. Remove the four screws holding the instrument cluster. Pull the cluster forward enough to allow access to the wiring connectors.


Fig. Fig. 9: The instrument cluster is retained by four screws

  1. Disconnect the wiring harnesses and remove the instrument cluster.
  2. Individual instruments may be removed from the cluster after it is removed from the car. Avoid damage to any terminals or the printed circuit board.

To install:
  1. Install the gauge cluster; connect the wiring before it is fully in place. Install the retaining screws.
  2. Install the instrument panel. Make sure it is correctly placed. Install the retaining screws.
  3. If applicable, install the air vents.
  4. Install the coin box, switches and dash light controller.
  5. Install the radio, ashtray holder and ashtray.
  6. Install the console.
  7. If applicable, enable the SRS.
  8. Connect the negative battery cable.

My dash board milage light does not display

Probably a bad solder connection on the instrument panel between the led display and the circuit board itself. Instrument panel needs to be removed for this proceedure. Remove the back cover from the circuit board and carefully remove the circuit board to access the led display. Carefully lift up the display and look to see if any of the solder joints from the solder legs are loose. resolder as needed. Plug the circuit board in the dash and turn on the key to see if it works.

2000 olds silhouette - everything electric works strong but no instrument panel and won't start

It is possible that there is a circuit problem in the circuits that provide power and ground to the Instrument Panel Cluster (IPC), or the IPC itself could be internally damaged. The not starting problem is a direct result of the IPC not working. Your Engine Control Module (ECM) will not allow fuel or spark to the engine if the IPC cannot communicate. This is part of the security system that keeps theives from stealing parts out of your vehicle and using them in another vehicle. When you turn on the ignition switch, the IPC is supposed to communicate with the ECM and send it a security code. If the ECM does not recieve this security code from the IPC, it "assumes" that the IPC has been stolen and disables the engine to prevent the whole car from being stolen. If the IPC is replaced, the ECM has to be reprogrammed to accept the new security code from the new IPC.

My whole dash went off no lights the techmonotor doesn't work none of the gagues?

Sounds like you may have a blown fuse for your instrument panel assembly, open your fuse box and read on the cover the location of your instrument panel fuse pull it out with the fuse puller and see if its blown it its blown replace the fuse with the SAME amperage fuse you removed, your gauges should work again, if the fuse is good check the plug going into the back of the cluster and make sure its secure and clean, if your fuse is blown and you replace it with another fuse and it right blows again theres a short in the wiring for your instrument cluster circuit and further diagnosing will be required to locate and fix a potential short....

Instrument panel gauges all stopped working while driving.

These vans are common for having cracked circuit boards in the Instrument cluster. You need to replace the circuit board. Try smacking the end of the dash and see if the gauges start working again.

Dash lights not working

Typical problem, the old failed solder joints on the back of the instrument gauge circuit board. You;ll have to remove the instrument cluster and carefully remove the circuit card (board) and locate the two regular rows of solder joints on the front side (inside) opposite the connector in the center. Reflow the solder with q low wattage soldering iron 25-35 watts and the problem disappears after re-installation.

The bulbs plug into a printed circuit board, I suspect they have come loose, pull the cluster and see if they are loose or burned out.
