Dodge Magnum & Chrysler Aspen Key Fob Replacement Arlington TX
Dodge Magnum or Chrysler Aspen key fob replacement in Arlington TX, cut from VIN and programmed on site for $150–$320 in 2026. (682) 413-8193.
As of August 2026, a replacement key or fob for a Dodge Magnum or Chrysler Aspen in the Arlington area runs about $150–$260 as a spare with a working key present and about $200–$320 when all keys are lost. Both were built in the mid-2000s, both are long out of production, and both are genuinely easy vehicles to key because they share their security architecture with an enormous number of other Chrysler products. Call or text (682) 413-8193 with the year and we will confirm the exact figure.
Two orphans with a very common heart
The Dodge Magnum was built from 2005 to 2008 — the wagon sibling of the 300 and the Charger, on the same LX platform. The Chrysler Aspen ran from 2007 to 2009, a full-size SUV closely related to the Dodge Durango of the same era.
Neither sold in huge numbers, and both are the kind of vehicle a dealership service writer has to look up. That leads owners to assume keys are a problem. They are not, for one specific reason: neither vehicle got a bespoke security system. Both use the Sentry Key immobilizer family that Chrysler fitted across essentially its whole range in that period, which means the tooling, the blanks and the procedures are all mainstream.
The practical translation is that an "orphan" badge on the tailgate has almost no bearing on what a key costs.
Which key does yours have?
There are two possibilities in this era and they are easy to tell apart in your hand.
A metal blade key with a black plastic head. A transponder key. The chip in the head authenticates to the immobilizer; the blade turns the ignition cylinder. Some versions have remote lock buttons built into the head.
A chunky black remote with no exposed blade, which slides into a slot in the dash. A FOBIK. This appears toward the end of the Aspen's run and on later LX vehicles. If your ignition has a slot rather than a keyhole, this is what you have.
| Key type (Magnum / Aspen) | Arlington locksmith | Dealer |
|---|---|---|
| Blade key cut from VIN, no chip | $60–$130 | $90–$180 |
| Transponder key, spare with a working key | $150–$260 | $250–$380 |
| Transponder key, all keys lost | $200–$320 | $320–$480 + tow |
| Remote-head key, remote functions programmed | $180–$290 | $300–$430 |
| FOBIK, spare with a working key | $180–$320 | $300–$450 |
| FOBIK, all keys lost | $260–$420 | $400–$600 + tow |
These are 2026 ranges for a mobile visit inside our Arlington service radius. Every quote is confirmed against your VIN before we dispatch — that is what turns a range into a number.
The parts question, honestly
This is where being a low-volume, out-of-production vehicle does have an effect, and it is worth being straight about it.
Transponder blanks: no problem. These are commodity parts shared across a huge range of Chrysler products of the era. They are inexpensive and widely available.
Remote heads and FOBIKs: check the part number. The remote side is more model-specific. Aftermarket equivalents exist and generally work well, but the button count and layout have to match your original, and the internal frequency has to be right for your year.
Cosmetic shells: worth knowing about. If your existing fob works electronically but the housing has split — extremely common on a twenty-year-old vehicle — the board can often be transferred to a new shell for a fraction of the price of a programmed replacement. The programming stays intact because the electronics never change. Nobody volunteers this option, so ask for it.
"The Magnum and Aspen calls almost always start with the customer apologizing for having an unusual car. There is nothing unusual about the key. It is the same system as half the Chrysler products of that decade." — Arlington Auto Locksmith lead automotive technician
What all-keys-lost looks like on these
No original key is needed. Your vehicle's key code is derivable from the VIN through licensed channels, so a blade is cut to factory specification from scratch. Our VIN-cut car keys guide explains the process.
With a blade that turns, the transponder side follows. We connect at the diagnostic port, gain security access to the immobilizer module and write the new credential into the vehicle's accepted list. On this generation there is typically a documented waiting period before a first key can be accepted — designed in by the manufacturer, not padding, and impossible to shorten with any tool.
Expect forty-five to seventy-five minutes at the vehicle for a full all-keys-lost job. The lost car key replacement guide covers the visit in detail, and the related Chrysler 300 platform guide is directly relevant to Magnum owners, since it is the same LX car underneath.
The wear problem on twenty-year-old vehicles
Both of these are now old enough that the key is rarely the only thing that has aged.
Worn ignition cylinders. A key used daily for eighteen years and a cylinder used daily for eighteen years wear each other out together. The symptom creeps: jiggling, then jiggling every time, then a key that will not return from accessory. If a freshly cut key from the VIN turns easily and the old one does not, you have caught it in the cheap window. Our ignition repair guide for the Chrysler family covers the repair.
Split fob housings. Nearly universal at this age, and cheaply fixed with a shell swap as described above.
Weak twelve-volt batteries producing false symptoms. Worth ruling out before assuming a key or module fault — these vehicles produce convincing nonsense when voltage is low. Our rundown of why car keys stop working covers the common overlaps.
North Texas is hard on all three. Summer dust works into lock cylinders, and cabin heat is unkind to two-decade-old plastics and adhesives.
Locksmith or dealer for a vehicle this age?
For a Magnum or an Aspen, this is one of the clearer calls in the whole category. Dealer service departments are organized around vehicles under warranty, and many no longer stock anything for a 2007 Aspen — which means a call there frequently ends in a special order and a wait, on top of a tow if the vehicle cannot start.
Mobile service inverts that. The blanks are commodity parts we already carry, the programming happens at the vehicle, and nothing has to move. Our full comparison of a mobile locksmith versus the dealership covers where each genuinely wins — there are cases where the dealer is right, and this is not usually one of them.
The Federal Trade Commission recommends getting repair estimates in writing before authorizing work. Ask specifically whether the quote covers the blank, the cutting, the programming and the service call. Texas locksmith companies are licensed through the Texas Department of Public Safety Private Security Program, and you should expect to show identification and proof of ownership before anyone keys your vehicle.
While we are there
Make two. Most of the cost of the visit is the visit, not the second blank. Two keys on a vehicle this age is cheap insurance, and our car key duplication service is the right line for it.
Ask about the shell swap if your fob works but looks destroyed.
Have the ignition checked with the fresh key while a technician is standing there. Five minutes now, potentially several hundred dollars later.

Frequently Asked Questions
Can you still make keys for a Dodge Magnum or Chrysler Aspen?
Yes, and they are among the more straightforward vehicles we key. Both use the Sentry Key immobilizer family that Chrysler fitted across nearly its entire range in that period, so the blanks, tooling and procedures are all mainstream despite both models being long out of production. Being a low-volume vehicle affects the remote housing far more than it affects the key.
How much does a Dodge Magnum or Chrysler Aspen key cost in Arlington?
As of 2026, a transponder key runs about $150–$260 as a spare with a working key present and about $200–$320 when all keys are lost. A FOBIK-style key, fitted to later vehicles with a slot instead of a keyhole, runs about $180–$320 as a spare and $260–$420 all-keys-lost. A plain blade key cut from the VIN is $60–$130.
My fob housing is cracked but the buttons still work. Do I need a new fob?
Probably not. If the electronics are healthy, the internal board can usually be transferred into a new shell for a fraction of the cost of a programmed replacement, and the programming survives because the electronics never change. Very few shops volunteer this option on an older vehicle, so it is worth asking for directly.
Do I need to tow my Magnum or Aspen to get a key made?
No. The key blade is cut from your VIN and the programming is done at the diagnostic port, both of which happen wherever the vehicle is parked. That is precisely why mobile service tends to be the cheaper answer on an older vehicle — the tow that a dealer visit would require never enters the equation.
How do I tell whether I have a transponder key or a FOBIK?
Look at the ignition. If you insert a metal blade and turn it in a keyhole, you have a transponder key with a chip in the plastic head. If you slide a chunky black remote with no exposed blade into a slot, you have a FOBIK. The two are different parts at different prices, and it is the single most useful thing to tell us on the phone.
Is a locksmith cheaper than the dealer for a vehicle this old?
Usually clearly so. Dealer service departments are organized around vehicles under warranty and many no longer stock parts for a 2007 Aspen, which turns the call into a special order and a wait — on top of a tow if the vehicle cannot start. A mobile locksmith carries the commodity blanks these vehicles use and programs at the vehicle.
