Nissan Sylphy matches keys through a password. More information about Sylphy key matching is as follows: 1. The password can be read with a special instrument, and the owner needs to provide documents: Password reading does not require disassembling any parts, but the owner needs to provide ID card, driving license, and other documents to read the password. 2. Key matching can choose between keys with start function and keyless start keys: After reading the password, keys can be matched. The price for matching a key is about two to three hundred, while matching a keyless start key costs about five to six hundred. The remote key can conveniently unlock and lock the car from a distance during both day and night without the need to locate the keyhole.

Matching Nissan Sylphy Key. I've handled this several times myself and found the key is to operate with both the original car key and the new key together. Sit in the driver's seat, ensure all doors are closed and locked. Within ten seconds, insert the original key, turn it to the ON position (do not start the engine) three times, and leave it in the ON position for three seconds on the third time. The doors will flash to confirm entering programming mode. Take out the new key, press and hold the unlock or lock button for a few seconds. If the car lights flash twice, it indicates successful matching. The whole process must be quick and uninterrupted, otherwise, start over. If you don't have the original key, you can only go to the 4S store to solve it with a diagnostic computer, which costs more but is safer. Check that the key battery has sufficient power to avoid matching failure and delays. Maintain the key properly, avoid dropping or getting it wet to extend its service life.

Last time I lost the key to my Nissan Sylphy, I researched the matching method myself. First, insert the original key into the ignition switch, turn it to ON six times within five seconds, and finally leave it in the ACC position. The doors will lock once to indicate readiness. Press any button on the new key within one second for a response, and the flashing light confirms successful matching. Be careful not to exceed the time limit—I failed once before by not paying attention to the seconds. The entire process is completed inside the car without starting the engine, ensuring the battery has sufficient charge. If matching fails, it might be a system issue or incompatible key. Visiting a repair shop with professional tools for debugging can save time and money. In daily use, avoid mixing keys with metal objects to prevent signal interference.
