FAQ
TL;DR: On Volvo FH 2010, losing remote pairing can mean a PLN 1,200 controller replacement; "You need a second efficient remote control." Quick battery swaps reduce unpairing risk; if decoded, coding needs two remotes or dealer tools. [Elektroda, lukasz56, post #18774842]
Why it matters: This helps Volvo FH 2010 owners restore remote locking after a dead battery or module unplug without wasting time or money.
Quick Facts
- Re-coding typically requires two working remotes due to a security lockout that blocks adding unknown remotes. [Elektroda, lukasz56, post #18774842]
- Swap the coin cell fast; prolonged removal can decode the remote and break pairing. [Elektroda, lukasz56, post #18774842]
- The “5x ignition ON, hazards flash” DIY sequence did not work on the reported FH 2010 case. [Elektroda, lukasz56, post #17207259]
- Dealer quoted a new controller with two remotes at approx. PLN 1,200 net when coding failed. [Elektroda, lukasz56, post #18774842]
- No tester? Use a radio: press the remote near the speaker and listen for crackle as a quick TX check. [Elektroda, lukasz56, post #17207294]
How do I reprogram a Volvo FH 2010 remote after a battery change?
If the remote unpaired during a slow battery swap, you need two working remotes or dealer-level programming. The system blocks adding unknown remotes without an already paired unit. If you only have one remote, coding may fail. In that case, service may recommend replacing the controller and supplying two matched remotes. Fast battery swaps help avoid this situation next time. Test the remote first to confirm it transmits before pursuing coding. [Elektroda, lukasz56, post #18774842]
Whats the safe way to swap the remote battery without losing pairing?
Prepare the new cell before opening the remote. Swap the old cell for the new one quickly to avoid power-loss timeout. Verify operation immediately near the truck after the swap. This minimizes the risk of the remote decoding and losing pairing. If it still fails, assume it unpaired and plan for re-coding with a second working remote or dealer support. "Do it quickly; take one battery out and put in the other." [Elektroda, lukasz56, post #18774842]
Does the five-times ignition ON hazard-flash method work on FH 2010?
A user tried the sequence—turn ignition to ON five times until hazards flash—and it did not work on their FH 2010. The hazards never confirmed programming mode. If this fails, the remote likely needs coding with an existing paired remote or dealer tools. Consider that unplugging modules can complicate pairing. Do not repeat the cycle endlessly; verify your remote transmits first. Quote: "turn the ignition switch to the ON position five times." [Elektroda, lukasz56, post #17207259]
Can I pair a single remaining remote, or do I need two?
You generally need a second already working remote. The system prevents adding unknown remotes, described as a "Volvo security feature." With only one unpaired remote, coding attempts may fail. Owners reported needing dealer help or a new controller kit that arrives with two paired remotes. Plan to secure a second good remote before attempting DIY programming steps.

Remote dead after battery swapwhat should I check first?
Confirm the coin cell polarity and seating. Ensure the plus and minus are oriented as marked in the holder. Clean the contacts gently if tarnished, then retest near the truck. Battery misplacement is a common first-time error and mimics a dead remote. If it remains unresponsive, proceed to a transmit check with a radio or tester. [Elektroda, mariann, post #17205967]
How can I test the remote without a dedicated RF tester?
Use a basic radio as a quick check. Place the radio near the remote's PCB or case speaker area. Press the remote button and listen for a crackle or buzz in the speaker. Consistent noise suggests the remote is transmitting. Absence of any noise points to a dead transmitter or battery issue. This is not a calibrated test, but it can confirm basic activity. [Elektroda, lukasz56, post #17207294]
Which fuse should I check for central locking if the remote stopped?
Inspect the central locking fuse in the truck's fuse panel before deeper diagnostics. A blown fuse disables locking, regardless of the remote state. Replace only with the specified rating to avoid module damage. If the fuse tests good and the remote worked before the battery change, focus on the remote and pairing. A fuse check is a quick, low-cost elimination step. [Elektroda, Anonymous, post #17204806]
I unplugged the alarm/central locking module; did that erase my remote?
After unplugging the module near the LCM, the remote may no longer be recognized. The reported ignition-cycling method failed to re-enter programming mode on FH 2010. Expect to need a paired second remote or dealer programming to restore locking. Avoid disconnecting the controller during troubleshooting unless necessary. If done, plan for potential re-coding. [Elektroda, lukasz56, post #17207259]
Dealer couldnt program my original remotewhat are my options and cost?
One owner reported the dealer could not assign their original remote back to the controller. The proposed solution was a new central locking controller with two remotes for about PLN 1,200 net. This is the edge case when coding fails and security blocks additions. Budget accordingly if you lack a second working remote. [Elektroda, lukasz56, post #18774842]
How do I know if the controller sees my remote?
Verify the remote transmits first, using an RF tester or a simple radio crackle check. If it does not transmit, the controller cannot see it. If it does transmit and there is no response, pairing may be lost. At that point, plan for coding with a second paired remote or dealer tools. "Check with the tester if the remote 'transmits'?" [Elektroda, CameR, post #17207286]
Is there a DIY procedure to code a second remote on FH 2010?
The thread does not confirm a working DIY sequence. The commonly cited five-ignition-cycle method did not enter programming mode in this FH 2010 case. Consider that later systems can require dealer-level tools or a known paired remote to add another. Without confirmation, avoid repeated attempts and test the transmitter first. [Elektroda, lukasz56, post #17207259]
Should I repair the remote hardware before attempting coding?
Yes. If the remote does not transmit or power up, coding cannot succeed. Inspect the PCB, switch domes, and battery contacts, then repair as needed. Replace the cell with a fresh, correct type. After confirming transmission, attempt coding steps or consult a dealer. Expert advice was blunt: "Fix the remote!" [Elektroda, CameR, post #17204073]
