Introduzione

I tasti del telecomando a portachiavi della mia Subaru non funzionavano più bene, quindi ho deciso di sostituire la batteria all'interno.

Questa procedura è relativamente semplice e gli stessi principi di base possono essere applicati alla maggior parte dei portachiavi di altri marchi.

    • Svita la vite sul retro della chiave usando un cacciavite a croce Phillips #1.

    • I due pezzi in plastica nera dovrebbero separarsi, svelando il modulo di controllo. Solleva il modulo di controllo dal resto della chiave.

    • Ci sono quattro ganci di bloccaggio in plastica che tengono insieme il modulo di controllo.

    • Iniziando dal gancio più piccolo, infila la parte piatta di uno spudger tra i pezzi di plastica bianca e nera del gancio per rilasciarlo.

    • Ruota il modulo di controllo al prossimo gancio, stando attento a non richiudere per sbaglio quello precedentemente rilasciato. Ripeti la stessa procedura del punto precedente per rilasciare gli altri ganci di bloccaggio.

    • Una volta rilasciati i quattro ganci, separa il pezzo di plastica bianca dal resto del modulo di controllo.

    • La batteria CR1620 è tenuta ferma da dei contatti in metallo. Usa la punta di uno spudger per rilasciarla.

    • Sostituisci la batteria con una nuova CR1620 ed assicurati che sia tenuta ferma dai contatti in metallo.

    YMMV, because the battery I had to replace was not a CR2025, but a CR1620. Seems like I'm not the only one :)

    • Opzionale: Usa la punta dello spudger per rimuovere la sporcizia accumulatasi nella chiave.

    • Reinfila il modulo di controllo nella chiave, assicurandoti che tutti i tasti siano allineati coi fori.

    • Riattacca le due metà del portachiavi iniziando dalla parte opposta alla chiave, continuando quindi fino a richiudere del tutto l'intero portachiavi.

    • Non dimenticarti di riavvitare la vite a croce Phillips!

    I found a 1616 battery in my "collection" followed the authors directions using micro screw driver for a spludger and the key fob for my 2006 Honda CR-V is again working. I shall buy a couple (or more 1616 batteries tomorrow. Thanks to the author for these instructions.

    Ok I changed the battery but it wont work unless I put in a pin code whilst the key is in the ignition help

All fine and good, except the identical looking key fob from my 2010 Outback uses a CR1620 battery. So much for the CR2025s I bought!

janetsutton -

Nice, clear description of the process (which is very simple). My 2010 Outback also uses the CR1620 battery, not the CR2025 the instructions say. I would recommend disassembling your key fob and taking the old battery to the store to compare. You can still drive with the disassembled key fob; you just have to lock/unlock the door manually.

Mark Ray -

Great instructions! However, just like Mark and Janet, my 2010 Legacy keys had a CR1620 battery. Also, there were 4 plastic clips on step 2. Thanks for the guide!

Steve Osgood -

Apparently the instructions have been updated since the above comments, because they now call for the CR1620, which is what I bought, and they work perfectly!

The instructions and photos are very clear, easy to follow, and accurate. I was very pleased to find this site and realize that for about 15 bucks total I could replace the batteries in both our 2010 Outback keys - I had imagined we'd have to get new keys or at the least take them to the dealer for a highly pricey replacement. Thanks, ifixit!!

Question, I replaced mine but it still doesn't work. do I need to reset the system?

Jessica Fraley -

According to another web page on this topic, it reads: "After the battery is replaced, the transmitter must be synchronized with the remote keyless entry system’s control unit. Press either the LOCK or UNLOCK button six times to synchronize the unit."

12amrider -

Thanks, this worked perfectly for me. No synchronizing needed, maybe because the battery was only out for a few minutes.

I replaced the battery in the 2012 Outback key but now the car won't do anything. its as if i triggered some system lock up and nothing works even with another key fob. what now?

Randy Dennis -

Did u get your key working, if yes how?

Leesa Scanes -

My screw immediately stripped and I could not use a screwdriver. Must have been a really cheap screw. I had to carefully drill the head off. Then I cut away some of the plastic holding the key so I could use a needlenose to turn the remaining screw part out. I replaced the battery and found a replacement screw that fit from an old laptop casing.

Steve Dodell -

Great write up except I have the push start/keyless start on my 2015 WRX and not this key.

Paul Cahill -

I ordered the tools suggested above, and the Phillips screwdriver is too big for my Honda CR-V 2010 key.

Kathryn McNulty -

Hi There,

I replaced the battery and now the FOB won’t do anything. When I unlock the door manually the alarm goes sounds until I put the key in the ignition and turn to the on position.

mtd0809 -

I have a 2007 Aveo and my car fob does not have 4 clips.' Do not know how to take the battery out.

Was able to replace my Lexus Key fob with a 1632 and my wife’s Honda 2032. This tutorial helped the process a lot. Thanks ifixit!!
