Titan Secure vs factory immobilizers:
when the key is the weak spot.
A factory immobilizer checks for a recognized key before the engine will run. That ended hot-wiring for most cars, and it's why thieves now go after the key instead.
In a relay attack, thieves pass on the signal from your key fob inside the house, and the car treats it as the real key. Key programmers use the car's diagnostic access to add a new key in minutes, and the car treats that one as genuine too. The alarm sounds at the car, which helps only if someone nearby acts on it.
Titan doesn't replace the factory immobilizer. It adds a separate layer that doesn't rely on the key: when it's armed, the car won't drive away, key or no key, and you get tamper alerts by app, email or SMS.
Keep the factory immobilizer, but don't rely on it alone. Thieves have moved on to attacking the key, and Titan is the layer that doesn't trust it. If your car would be hard to replace, add Titan.
See Titan on your vehiclesA factory immobilizer and alarm and Titan, point by point.
| Factory immobilizer and alarm | Titan Secure | |
|---|---|---|
| What it checks | That a recognized key is present | Whether Titan is armed, whatever key is used |
| Relay attacks | A relayed fob signal looks like the real key | A relayed signal doesn't move an armed vehicle |
| Cloned or newly programmed keys | A key programmed through the diagnostic port is treated as genuine | A cloned key doesn't move an armed vehicle |
| Alerts | The alarm sounds at the car | Tamper and movement alerts by app, email or SMS |
| Location | Only with a connected-car service | Live location and trips over GPS and LTE |
| Installation | Built in at the factory | Integrated by trained fitment engineers, usually in about 45 minutes |
Where a factory immobilizer and alarm is enough
- It's the baseline every modern car should have, so keep it.
- It's enough against hot-wiring and forced ignitions, the methods thieves used before they went after the key.
Why Titan wins
- Your model is a common target for relay attacks or key programming.
- You want to know when someone tampers with the car, wherever you are.
- You want live location and trips without a connected-car subscription.
- You protect a lot or a fleet and want every vehicle armed on a schedule.
Using both: Keep both. The factory immobilizer and alarm are your first layer; Titan is a second one that doesn't depend on the key.

Talk to Our TeamDoesn't my car already have an immobilizer?
Most modern cars do, and it stops the engine running without a recognized key. The trouble is that thieves now attack the key itself, with relay attacks and key programming, so the immobilizer sees a key it accepts.
Is Titan better than a factory immobilizer?
They do different jobs, and you want both. The factory immobilizer is a good baseline, but it trusts the key, and the key is what modern thieves attack. Titan doesn't trust the key: when it's armed, the car won't drive away, whatever key is used.
What is a relay attack?
Two thieves work together. One holds a device near your key fob, often through a door or window at home, and the other holds a device by the car, which picks up the fob's relayed signal, unlocks and starts. In a 2016 test by the National Insurance Crime Bureau, one such device opened 19 of 35 vehicles and started and drove away 18.
Is my car alarm enough?
Rarely on its own. An alarm sounds at the car, so it helps only if someone nearby hears it and acts. And a thief using a relayed signal or a programmed key may not set it off at all, because the car thinks it's being opened normally. Titan sends tamper alerts to your phone and keeps an armed car from driving away.
Were some Hyundai and Kia models sold without immobilizers?
Yes. Many 2015 to 2019 model year Hyundai and Kia vehicles had no electronic immobilizer, which made them easy targets. In February 2023 the companies announced free anti-theft software upgrades for about 8.3 million US vehicles.
Does Titan replace my factory immobilizer or alarm?
No. Titan adds a separate layer of prevention alongside them. It doesn't depend on the key, so a relayed signal or a cloned key doesn't help a thief move an armed vehicle.
