How to access the Saab TWICE module
General under-seat access and removal information for compatible older Saab 9-3 and Saab 9-5 models.
TWICE position and module photographs
These photographs show the TWICE unit beneath the carpet and the module removed from the vehicle.
Two illustrated views of the TWICE location
TWICE is below the carpet and left front seat. These are original explanatory diagrams, not photographs. The exact trim and fastening arrangements depend on year, model and seat specification.
Front seats may include side airbags, belt pretensioners, occupancy sensing and memory wiring. Incorrect removal can cause injury or faults. Use the applicable Saab workshop manual, follow battery-disconnection requirements, allow at least 30 minutes before SRS work and never probe or short an airbag connector. Have a trained technician do this work if in doubt.
TWICE removal procedure
- Confirm the exact Saab model and location of the TWICE. Some vehicle and seat variations require different trim removal.
- Switch the ignition off. Set the seat position so its mounting fasteners are accessible before disconnecting power, following the manufacturer's procedure.
- Remove front and rear seat-rail mounting fasteners in the correct order and safely disconnect any under-seat connectors; lift out the seat without stressing the wiring.
- Release the left-hand sill/scuff trim, then carefully lift the edge of the carpet and sound insulation to reveal the floor-mounted TWICE unit.
- Where a ventilation duct covers the unit, undo its fastener and raise or move the duct sufficiently to reach the TWICE fixings.
- Remove the unit's mounting nuts/bolts, unlock the large electrical connector, and lift the module without pulling on the harness.
- Keep the unit dry, protect all connectors and wrap it securely. Include your name, telephone, email and return address when sending to our UK address.
TWICE module removal instructions
These additional details are taken from the SAABKEYS removal guidance. They describe the arrangement on certain older Saab 9-3 and 9-5 models. The correct Saab workshop procedure and seat/airbag precautions take priority.
- Use a Torx T-40 bit and ratchet to remove the four seat bolts securing the left front seat to the floor. The bolts may be tight because of thread-locking compound. Following the correct SRS isolation procedure, disconnect the seat-memory and side-airbag harness, where fitted, using the connector's burgundy release clip. Move the seat rearwards into the rear-seat area without straining the seat belt or wiring.
- Lift off the door-sill trim.
- Lift the carpet to expose the floor heater ventilation duct and the TWICE area beneath it.
- For the illustrated arrangement, release the plastic rivet by pressing its central button, remove the 10 mm plastic nut securing the floor vent, then lift the vent clear of the TWICE module.
- Remove the TWICE mounting nut or nuts. The earlier guide described one 10 mm plastic nut on certain Saab 9-3 models and three on certain Saab 9-5 models; check your specific car before proceeding.
- Operate the release handle on the wiring-harness plug to disconnect it without pulling on the wires.
- Remove the module carefully, protect it for shipping and post it to SAABKEYS with your full contact details and return address.
Additional professional programming required: None. Plug and drive — only for agreed compatible work where we programme matched keys or transponders to that car's original TWICE module.
For a Saab 9-5, the procedure may involve several 10 mm fasteners; do not assume the quantity or arrangement is identical on every Saab 9-3 or year. Always check the manufacturer's specific procedure.
