So, you’ve got a 2003 Nissan 350z and need to program a new key fob? It’s a common situation, especially if you’ve purchased a replacement online or are adding an extra remote for convenience. Many 350z owners find themselves in this position and thankfully, programming a key fob for your Nissan 350z can often be done at home without a trip to the dealership. Let’s walk through the process to get your new key fob working with your 2003 Nissan 350z.
The programming sequence for the 2003 Nissan 350z key fob is relatively straightforward, but it’s crucial to follow each step precisely. Here’s a detailed guide to help you program your key fob:
-
Turn the ignition switch from Position 0 to ON 6 times within 10 seconds. This initial step is critical for initiating the programming sequence. Make sure you are moving the key quickly and smoothly between the OFF and ON positions.
-
Then turn ignition switch to OFF position. Leave key in ignition switch. After the rapid ignition cycling, switch the ignition off but leave the key inserted. This prepares the system to enter programming mode.
-
After 2 seconds, the system will enter programming mode and will flash the warning lights twice. This is the confirmation you’re looking for. Keep an eye on your dashboard; the hazard lights should blink twice to indicate that your 350z is now in programming mode and ready to accept the new key fob signal.
-
Press and HOLD the unlock button on the Plip. Now, take your new key fob. Locate the unlock button and press and hold it down.
-
While pressing the unlock button, press the lock button 3 times. Keep holding the unlock button and, while doing so, press the lock button on the key fob three times in quick succession.
-
Release the unlock button. Let go of the unlock button.
-
The warning lights will flash once to indicate successful programming. Watch the hazard lights again. A single flash confirms that the key fob has been successfully programmed to your 2003 Nissan 350z.
-
Repeat procedure 4 to 7 for up to 4 plip key’s. If you have additional key fobs to program, repeat steps 4 through 7 for each one. This process allows you to program up to four key fobs to your Nissan 350z.
-
When completed turn ignition ON, and the warning lights will flash 2 times. Once you’ve programmed all your key fobs, turn the ignition to the ON position. The hazard lights should flash twice to signal the end of the programming sequence.
-
Remove key, and check all plip key’s for operation. Finally, remove the key from the ignition. Now, test each of your programmed key fobs to ensure they lock and unlock your 2003 Nissan 350z correctly.
Many 2003 Nissan 350z owners, like the user in the original post, sometimes encounter issues at step 3, where the warning lights fail to flash twice. If you’re experiencing this problem, double-check that you are performing step 1 correctly and within the 10-second timeframe. Ensure the ignition is turned completely to the ‘ON’ position each time and back to ‘0’ or ‘OFF’ position. Sometimes, a slight variation in timing or a less-than-firm turn of the ignition can prevent the system from entering programming mode.
If you continue to have trouble programming your 2003 Nissan 350z key fob, it might be worth considering factors like the key fob’s compatibility with your vehicle or potential issues with the vehicle’s security system. For further assistance or if you suspect a more complex problem, consulting a professional automotive locksmith or a Nissan dealership might be necessary.
