El Cid   212 #4 Posted January 1, 2018 My Rover 25 spare fob does not work : battery OK . Do you buy a new one and re programme ? Where from : how ?  https://www.ebay.co.uk/itm/OEM-2-BUTTON-REMOTE-KEY-ALARM-FOB-for-ROVER-MG-ZR-ZS-MGF-TF-25-45-etc-3TXB-/263237940401?_trksid=p2385738.m4383.l4275.c10  You need to know what you are buying. Sometimes they can clone your key, or they may need to plug their laptop into your cars CPU. A company came out to my Renault, reprogrammed 2 new keys and it took them less than 10 minutes, cost = £100 Share this post Link to post Share on other sites Share this content via...
alan p   15 #5 Posted January 1, 2018 Have a look at this site. ITSTILLRUNS.COM. They show you how to reset it. I haven’t used it so cannot guarantee it will work. Alan. Share this post Link to post Share on other sites Share this content via...
zigzag   10 #6 Posted January 1, 2018 Are you 100% sure the battery is good and in the right way around ? with the key out of the ignition press the unlock button multiple times it should sync if it is working , on some models pressing both unlock and lock buttons does the same trick.If this fails take it to lock smith (harolds is best) and they will check that it is sending a signal .If its dead it will be cheaper to buy an ECU /alarm module/fob set from ebay .You need all three as they are coded together ,about £30-£40 easy job to change takes about 20 mins . hope this helps.
