From what I found online, the ELVAT5G is part of the Securikey+ system. If you have a Valet Switch, look at the second method at the end of this post. Here are the 2 methods you can try and use to program your Transmitter:
PROGRAMMING ADDITIONAL or REPLACEMENT TRANSMITTERS
CHANNEL # FEATURE CONTROLLED BY THIS CHANNEL
1 Lock
2 Unlock
3 Trunk Release (optional kit required; not available on all models)
4 30 second headlight activation (only if required by GREEN button)
5 Remote panic (only if required by GREEN button instead of LOCKbutton)
6 Remote start (optional kit required; not available on all models)
To program new or additional transmitters, or when adding options to existing SECURIKEY+ transmitters, follow the step by step programming instructions found below. When programming, it is important to complete each step of the procedure within 15 seconds, or the system will terminate the programming mode. If this happens, simply start again.
-
Be sure that the SECURIKEY+ system is disarmed, and the lighted valet switch is in the off (out) position before you begin.
- Turn the vehicle's ignition key to the on position.
- Press then release the L.E.D. valet switch 6 times.
CHANNEL 1: LOCK & Panic Feature Horn Chirps 1 Time L.E.D. Flashes 1 Time
To program the LOCK button on the transmitter, press and hold the LOCK button until the vehicle's horn sounds one loud chirp. Repeat this for all transmitters that need the LOCK button programmed (up to four transmitters).
After the LOCK button on all transmitters have been programmed, press and release the L.E.D. valet switch 2 times to advance to the next receiver channel.
CHANNEL 2: UNLOCK Feature Horn Chirps 2 Times L.E.D. Flashes 2 Times
To program the UNLOCK button on the transmitter, press and hold the UNLOCK button until the vehicle's horn sounds one loud chirp. Repeat this for all transmitters that need the UNLOCK button programmed (up to four transmitters).
After the UNLOCK button on all transmitters have been programmed, press and release the L.E.D. valet switch 2 times to advance to the next receiver channel.
CHANNEL 3: TRUNK RELEASE Option Horn Chirps 3 Times L.E.D. Flashes 3 Times
To program the TRUNK RELEASE option on the transmitter, press and hold the GREEN option button until the vehicle's horn sounds one loud chirp. Repeat this for all transmitters that need the GREEN option button programmed (up to four transmitters).
After the TRUNK RELEASE button on all transmitters have been programmed, press and release the L.E.D. valet switch 2 times to advance to the next receiver channel.
CHANNEL 4: 30 SECOND HEADLIGHT Feature Horn Chirps 4 Times L.E.D. Flashes 4 Times
To program the HEADLIGHT option on the transmitter, press and hold the GREEN option button until the vehicle's horn sounds one loud chirp. Repeat this for all transmitters that need the GREEN option button programmed (up to four transmitters).
After the HEADLIGHT button on all transmitters have been programmed, press and release the L.E.D. valet switch 2 times to advance to the next receiver channel.
CHANNEL 5: Separate PANIC Button Feature Horn Chirps 5 Times L.E.D. Flashes 5 Times
To program the PANIC option on the transmitter, press and hold the GREEN option button until the vehicle's horn sounds one loud chirp. Repeat this for all transmitters that need the GREEN option button programmed (up to four transmitters).
After the PANIC button on all transmitters have been programmed, press and release the L.E.D. valet switch 2 times to advance to the next receiver channel.
CHANNEL 6: REMOTE START Feature Horn Chirps 6 Times L.E.D. Flashes 6 Times
To program the REMOTE START option on the transmitter, press and hold the GREEN option button until the vehicle's horn sounds one loud chirp. Repeat this for all transmitters that need the GREEN option button programmed (up to four transmitters).
After the REMOTE START button on all transmitters have been programmed, press and release the L.E.D. valet switch 2 times to advance to terminate programming mode, or simply turn the ignition key to the off position to terminate the transmitter programming mode.
If you have a Toggle Valet Switch try this:
To program new or additional transmitters,
1. Enter the vehicle, and turn the ignition key to the " on " position.
2. Flip the valet switch on - off - on - off - on - then off.
3. The dash L.E.D. will flash one time, and the siren will chirp one time, indicating the system is ready to accept programming for receiver channel 1.
4. Press and hold the selected transmitter button ( s ) until the siren sounds a long chirp, indicating the signal has been stored into memory.
5. If you have additional transmitters ( up to 3 ) that need to be programmed, repeat step 4 for each transmitter.
6. Flip the valet switch on then off.
7. The dash L.E.D. will flash two times, and the siren will chirp two times, indicating the system is ready to accept programming for receiver channel 2.
8. Press and hold the selected transmitter button ( s ) until the siren sounds a long chirp, indicating the signal has been stored into memory.
9. If you have additional transmitters ( up to 3 ) that need to be programmed, repeat step 8 for each transmitter.
10. Flip the valet switch on then off.
11. The dash L.E.D. will flash three times, and the siren will chirp three times, indicating the system is ready to accept programming for receiver channel 3. I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514
